a piece of writing: the text that was actually set down, whether cut into stone, engraved on metal, or sent as a letter
TranslatabilityApproximateCertaintyStrong
This noun is built straight off the verb "to write" (כָּתַב), and it names the result rather than the act. Not the writing of it, but the thing written. That is why one word can point at objects as different as a carved tablet and a king's memo.
What changes across its nine appearances is the surface and the purpose, not the core sense:
text cut into the stone tablets at Sinai
an engraving on the gold plate worn by the high priest
a letter carried to a king from a prophet
a royal decree sent out in writing as well as by voice
the heading over a poem a king wrote after recovering from illness
In every case the point is that the words were fixed rather than merely spoken, and so could be read again later by someone who was not there.
That contrast with a spoken word is exactly why the writers of Chronicles and Ezra reach for it. A proclamation shouted through a kingdom fades; the same order put in writing outlasts the moment it was announced, and can be produced again as proof. The weightiest use runs on the same logic: at Exodus 32:16 the text on the tablets is called the writing of God, and what makes it extraordinary is not the noun, which is entirely ordinary, but whose writing it is.

Isa 38:9*
Isa 38:9
Whether the Masoretic מִכְתָּב in the superscription of Isaiah 38:9 is original, or a scribal corruption of מִכְתָּם, the heading term of Psalms 16 and 56 to 60.
majorityRetain מִכְתָּב. The superscription calls Hezekiah's psalm a written composition, which is compatible with the noun's ordinary sense of a composed, fixed text, and there is no textual witness requiring emendation.; HALOT (Koehler-Baumgartner), s.v. מִכְתָּב; Hans Wildberger, Isaiah 28-39: A Continental Commentary (2002)
minorityEmend to מִכְתָּם. מִכְתָּב is nowhere else used as the heading of a poem, whereas מִכְתָּם heads six psalms, and the two differ by a single consonant, so the Masoretic form is most economically explained as a graphic error.; BDB (Brown-Driver-Briggs), s.v. מִכְתָּב; Otto Kaiser, Isaiah 13-39: A Commentary, Old Testament Library (1974)

How mikhtav differs from similar Hebrew words
כְּתָבthe plainer noun for a piece of writing, used above all for a script or a royal edict in Esther and Ezra; 2 Chronicles 35:4 puts the two words side by side in a single sentence.
מִכְתָּב points to a specific engraved inscription, words cut into an object such as the stone tablets or the gold plate worn on the priest's forehead.Exo 32:16Exo 39:30Deu 10:4
It names one concrete piece of writing, a particular letter or composition produced on a single occasion and identified as a single text.2Ch 21:12Isa 38:9Ezr 1:1
Both
Both words name an authoritative written prescription handed down by a king, as when the temple service is arranged by the written directions of David and of Solomon.2Ch 35:4
כְּתָב can name a formal register or enrollment, an official list of names such as a genealogy or roll, so that a person is either recorded in it or missing from it.Ezr 2:62Neh 7:64Ezk 13:9
It covers a royal edict or decree issued in writing and carrying the force of law, a public order sent out through the provinces to be obeyed.Est 3:14Est 8:8Est 9:27
It can mean the script or writing system itself, the set of characters of a given language, as when a decree is sent to each province in its own script.Est 1:22Est 3:12Est 8:9
סֵפֶרthe scroll or document as a physical object you can roll up, hand over, and store; this word names the text written on it rather than the object itself.
Names the marks themselves rather than the thing they sit on. On Sinai the stone tablets are one object and the writing cut into them is another, and the text is what gets credited to God.Exo 32:16Deu 10:4
Covers lettering cut into hard surfaces, with no roll, sheet, or document in view at all: the words engraved on the gold plate worn on the high priest's turban.Exo 39:30
Can mean writing as a way of communicating, set against speaking out loud. Cyrus sends his decree through the empire by voice and then also puts the same decree in writing.2Ch 36:22Ezr 1:1
Serves as the heading over a composition, naming the text as one man's words: the psalm Hezekiah wrote after his illness is introduced this way.Isa 38:9
Both
Both can name an official message sent from one authority to another across a distance. A message reaches King Jehoram from Elijah, and letters reach the king of Israel and the leaders of Samaria the same way.2Ch 21:122Ki 5:52Ki 10:1
Both hold words that outlast the moment and are looked up later as authority. Levites in Josiah's day arrange themselves by what David and Solomon set down, and the deeds of Solomon are cited from a record kept about him.2Ch 35:41Ki 11:41
Names an object you can pick up, seal shut, and put into a messenger's hands. David's orders about Uriah and Jezebel's orders about Naboth travel as sealed items, and Hezekiah takes one from the messengers and spreads it out before God.2Sa 11:141Ki 21:82Ki 19:14
Behaves like a physical thing in the world: it can be tied to a stone and thrown into the river, stored in a clay jar to survive for years, rolled up the way the sky is pictured rolling up, or dipped so the ink washes off into water.Jer 51:63Jer 32:14Isa 34:4Num 5:23
Works as a legal instrument that takes effect when it changes hands. A husband puts one in his wife's hand to end the marriage, and Jeremiah's land purchase is completed by handing over the sealed deed in front of witnesses.Deu 24:1Jer 32:11
Is the thing people read aloud from and keep in a set place. It is read out to the whole assembly and stored beside the ark, so the community gathers around the object itself.Exo 24:7Deu 31:26Neh 8:5
אִגֶּרֶתa letter in the narrow sense, an item of correspondence sent from one party to another, which is only one of the things this word can name.
Can name words cut into stone or metal rather than marked on a scroll, such as the words on the stone tablets or the letters on the gold plate of the priest's turban.Exo 32:16Exo 39:30Deu 10:4
Keeps the spotlight on whose hand produced the words, which is why the phrase regularly runs "the writing of" someone: God, David, Hezekiah.Exo 32:162Ch 35:4Isa 38:9
Points at the wording itself, so it can head up a poem as its title or record the exact terms of an announcement once they are set down on paper.Isa 38:92Ch 36:22Ezr 1:1
Both
Both can name a document that travels from one person to another and reaches the recipient as a message he must answer for, which is why English Bibles render each of them "letter" in these places.Neh 2:72Ch 21:12
Both name something written down to outlast the moment, so a later generation can look it up and act on it, whether that is the record of how a festival began or the standing instructions of an earlier king.Est 9:262Ch 35:4
Names mail in transit: the document is handed to runners, carried across the country, and put into someone's hand, so the word covers the whole trip from sender to recipient.2Ch 30:6Neh 2:9Neh 6:5
Works in both directions, so it can describe a running exchange of messages between two parties, with notes going out and answers coming back as a form of pressure.Neh 6:17Neh 6:19
Covers the paperwork of empire that a traveler presents to officials along the way, such as a safe passage permit or an order for building supplies.Neh 2:7Neh 2:8
מִכְתָּםthe label standing over six psalms, of uncertain meaning; it differs from this word by one letter, and some scholars read it in place of this one at Isaiah 38:9.
mikhtav in the other biblical languages
γράμμαGreek“something written”the Greek noun for something written, running from a single letter of the alphabet to a bill, a legal document, or the written law.
It names a royal order deliberately put in writing as well as proclaimed aloud, so that the command outlasts the herald. Cyrus sends his decree "and also in writing" through his whole kingdom (2 Chronicles 36:22,Ezra 1:1), and Josiah's temple arrangements follow what earlier kings had set down (2 Chronicles 35:4). The Greek word covers documents and dispatches but is never used this way for a king's published decree.2Ch 36:22Ezr 1:12Ch 35:4
It can serve as a title standing over a poem, labelling the piece that follows as something its author composed and set down: "a writing of Hezekiah" after his recovery from illness (Isaiah 38:9). The Greek word is never used as a heading for a composition.Isa 38:9
Both
Both name the finished text rather than the act of writing it, and both are at home with words cut into a hard surface. The Hebrew word describes the text on the Sinai tablets, called the writing of God (Exodus 32:16), and the Greek word describes the same tablets from the other side of the Bible as a ministry "engraved in letters on stone" (2 Corinthians 3:7).Exo 32:162Co 3:7
Both cover a written message carried from one party to another, where the point is that the words were committed to writing instead of merely spoken. Elijah's warning reaches King Jehoram as a letter (2 Chronicles 21:12), and the Jewish leaders in Rome tell Paul they have "received no letters" about him from Judea (Acts 28:21).2Ch 21:12Act 28:21
The Greek word can shrink to a single character of the alphabet, one mark on the page or the board. The sign over the cross was posted "in letters" of three scripts (Luke 23:38), and Paul points to the size of the characters he formed with his own hand (Galatians 6:11). The Hebrew word never names one character on its own; it always names the whole text.Luk 23:38Gal 6:11
In the plural it can stand for schooling itself, the training a person did or did not receive. The crowd is astonished that Jesus "knows letters" without having studied (John 7:15), and Festus tells Paul that his "great learning" is driving him mad (Acts 26:24). The Hebrew word stays with the written object and never turns into a word for education.Jhn 7:15Act 26:24
Paul turns it into a theological term for the written law as an outward code set against the Spirit: "the letter kills, but the Spirit gives life" (2 Corinthians 3:6), and true circumcision is "of the heart, by the Spirit, not by the letter" (Romans 2:29). Nothing like this charged use attaches to the Hebrew noun, which stays neutral about what is written.2Co 3:6Rom 2:29Rom 7:6
It reaches into everyday business paper, the private note that records what one person owes another. The dishonest manager hands each debtor his "bill" and tells him to write a smaller figure (Luke 16:6,Luke 16:7). The Hebrew word is used for public and official writing, never for a commercial IOU.Luk 16:6Luk 16:7
כְּתָבAramaic“inscription”the Aramaic noun used in Ezra and Daniel for a written decree or an inscription on a wall, covering the same official written text this word names in Hebrew.
Points at the marks themselves as a made thing, with the surface they were cut into and the hand that cut them both in view: letters engraved through stone tablets, or cut into a gold plate the way a seal is cut.Exo 32:16Exo 39:30Deu 10:4
Can head a piece of writing by the person who composed or sent it, working almost like a title line: a letter that arrives from a named prophet, or the record a king wrote down after recovering from illness.2Ch 21:12Isa 38:9
Both
Both name a ruler's order that carries weight precisely because it was put into writing, whether the king signs it so it cannot be undone or has his proclamation written out and circulated.Dan 6:8Dan 6:92Ch 36:22Ezr 1:1
Both can point back to an older written instruction that present practice has to match, which is why each turns up in accounts of setting the priests and Levites in their appointed places.Ezr 6:182Ch 35:4
Names a text that nobody present can make sense of, so the story turns on finding someone able to read it out and say what it means. The words are there in plain view, yet the king's advisers fail at them and a reader has to be summoned.Dan 5:7Dan 5:8Dan 5:15Dan 5:16Dan 5:17
Can be quoted directly, so that the writing itself is set down word for word and then unpacked piece by piece for the reader.Dan 5:24Dan 5:25
Can mean an amount fixed on paper in advance, so that supplying something with no writing attached means supplying it with no set limit.Ezr 7:22
What scholars say about mikhtav
A noun of the maqtāl pattern from the root כתב "to write," attested nine times in eight verses. BDB, HALOT and DCH all treat it as a single lexeme whose core sense is "something written," contextually specified as an inscription (Exodus 32:16; 39:30; Deuteronomy 10:4), a letter (2 Chronicles 21:12), or an authoritative written directive or edict (2 Chronicles 35:4; 36:22 = Ezra 1:1); none of the standard lexica divides it into homonyms. The juxtaposition with the simple noun כְּתָב in 2 Chronicles 35:4 (בִּכְתָב דָּוִיד ... וּבְמִכְתַּב שְׁלֹמֹה) indicates the Chronicler did not regard the two as fully interchangeable, though no consistent semantic distribution between them has been demonstrated across the corpus. The one contested occurrence is the superscription of Isaiah 38:9, where BDB proposes emendation to מִכְתָּם, the heading term of Psalms 16 and 56 to 60; HALOT and most recent commentators retain the Masoretic reading.
