one: the number one, and from it the word that marks a thing as single, whether counting it, picking it out of a group, or simply introducing it as "a" something
TranslatabilityApproximateCertaintySettled
This is the Aramaic word for the number one, at home in the Aramaic chapters of Daniel and Ezra where the rest of the Old Testament uses the Hebrew word for "one" (אֶחָד). Much of the time it counts exactly what you would expect: Daniel is one of the three officials set over the satraps, and the bear in his vision is propped up on one side.
The interesting part is how far it travels past plain counting. Four stretches account for most of its uses:
it does the work English does with "a", introducing something the reader has not met yet, such as a letter, a scroll, or a stone
it stands in for "first" in the date of a reign, so "year one of Cyrus" means the first year of his rule
paired with a second number it multiplies rather than counts, which is how Nebuchadnezzar orders the furnace heated seven times hotter than usual
with the small prefix meaning "like" it becomes an adverb, "as one", meaning everything at the same instant
What holds the range together is that the word is less about quantity than about singleness: one and not several, this one and not another, a one nobody has met before. Daniel leans on that force when he warns the king's advisers that only one verdict is waiting for all of them.

How ḥad differs from similar Aramaic words
קַדְמַיthe true Aramaic word for "first" in a sequence, used for the first of the four beasts; this word means "first" only inside the fixed formula for a king's first year.
It is the counting word. It says how many, or picks a single member out of a named group: Daniel is one of the three officials over the satraps, one of the figures standing by is the one Daniel approaches, and the bear is propped up on one side.Dan 6:2Dan 7:16Dan 7:5
It introduces something the reader has not met yet, doing the work English does with "a": a letter sent to the king, a scroll found in the archive, a stone brought to seal the lions' den.Ezr 4:8Ezr 6:2Dan 6:17
It stretches past counting altogether. Set beside a second number it multiplies, so the furnace is heated seven times hotter than usual; on its own it can mean all at once, when the pieces of the statue are crushed together in one moment; and it can mean only one and no other, as when the king warns his advisers that a single verdict is waiting for them all.Dan 3:19Dan 2:35Dan 2:9
Both
Both come into English as "first", which is where readers confuse them. The counting word carries it in the date of a reign, where "year one of Cyrus" and "year one of Belshazzar" mean the first year of that king, while the ranking word carries it for the first item in a lineup, the first of the four beasts.Ezr 5:13Ezr 6:3Dan 7:1Dan 7:4
It ranks rather than counts. It fixes an item's place at the head of a series that keeps going, so the first beast of Daniel's four is the one the vision starts with and a second, third and fourth follow it.Dan 7:4
It looks backward, and is regularly rendered "former" or "earlier": the horns already in place before the little one pushes up among them, and the kings who came before the one who rises after them.Dan 7:8Dan 7:24
It only ever describes something already in view. The beast, the horns and the kings are all named before it labels them, so it never brings a new thing into the story.Dan 7:4Dan 7:24
אׇחֳרָןthe natural partner in a list: one thing, then another, as Daniel counts off the beasts that come up out of the sea.
It is the number one, so it does the plain counting: dating an event to the first year of a reign (Ezra 5:13,Ezra 6:3,Daniel 7:1), measuring the single hour Daniel sat stunned (Daniel 4:19), heating a furnace seven times hotter than usual (Daniel 3:19), and telling us which side of the beast was propped up (Daniel 7:5).Ezr 5:13Ezr 6:3Dan 7:1Dan 4:19Dan 3:19Dan 7:5
It often does the work of the English word "a", simply introducing something for the first time with nothing set against it: a letter sent to the king (Ezra 4:8), a scroll turned up in the archives (Ezra 6:2), a stone laid over the mouth of the den (Daniel 6:17), a huge statue standing in the dream (Daniel 2:31).Ezr 4:8Ezr 6:2Dan 6:17Dan 2:31
It can gather separate things into a single mass, rendered "together" or "all at once": in Daniel 2:35 the iron, clay, bronze, silver and gold of the statue are shattered as one.Dan 2:35
Both
Both can stand on their own in place of a person, pointing at somebody the text never names and identifying him only by where he stands in a group: Daniel is "one" of the three officials set over the kingdom (Daniel 6:2), the dreamer steps up to "one" of those standing nearby (Daniel 7:16), and the royal gifts are to be handed to "another" instead (Daniel 5:17).Dan 6:2Dan 7:16Dan 5:17
It only works when something else is already in view, and it marks a second, different one set over against that first: the kingdom that will not be handed on to "another" people (Daniel 2:44), and the king who rises after the ten horns already counted (Daniel 7:24). Remove the first item and the word has nothing left to say.Dan 2:44Dan 7:24
It carries the sweeping denials, where the whole point is that no rival exists at all: there is no one else who can tell the king what he dreamed (Daniel 2:11), and no "other" god who can rescue the way this one just did (Daniel 3:29).Dan 2:11Dan 3:29
ḥad in the other biblical languages
אֶחָדHebrew“one”the Hebrew word for "one", covering the same ground everywhere outside the Aramaic chapters, including the famous confession that the LORD is one.
Only the Aramaic word is paired with a second number to say how many times over something is done, as when the king orders the furnace heated "seven times" hotter than usual.Dan 3:19
Both
Both are the ordinary counting word for the number one, and both are used for picking out "one of" a larger group.Gen 3:22Gen 42:13Dan 6:2Dan 7:16
Both stand where English says "first" in a date or in a king's opening year, because each language simply counts from one instead of reaching for a separate word.Gen 8:13Ezr 6:3Dan 7:1
Both can work much like the English article "a", bringing a single unnamed person or object into the story without naming or numbering it further.1Sa 1:11Ki 19:4Ezr 4:8Dan 6:17
Only the Hebrew word is used for two things becoming a single whole: a husband and wife made "one flesh", two sticks joined into "one stick" in the prophet's hand, two kingdoms made "one nation" again.Gen 2:24Ezk 37:19Ezk 37:22
Only the Hebrew word carries the confession that the LORD is one, the line Israel was told to say and hold onto, and the promise that on the coming day his name will be one as well.Deu 6:4Zec 14:9
Only the Hebrew word describes a whole population as sharing one speech or moving with a single will, so that the earth can have "one language" and a crowd can rise up "as one man".Gen 11:1Gen 11:6Jdg 20:8
חַדHebrew“one”the identical spelling turning up a single time in Hebrew, in Ezekiel, where it is widely taken as a borrowing from Aramaic.
εἷςGreek“one”the Greek word for "one", which likewise drifts toward "a certain one" and "someone" in ordinary New Testament narrative.
The Aramaic word can multiply instead of count. When Nebuchadnezzar orders the furnace heated "seven times" hotter than usual, the word for one is what turns seven into seven times over. The Greek word is never used this way in the New Testament.Dan 3:19
The Aramaic word can also mean "all at once". When the statue in Nebuchadnezzar's dream shatters, the iron, clay, bronze, silver, and gold break together in a single moment rather than one after another.Dan 2:35
Both
Both are the everyday word for the number one, simply counting a single thing: one scroll turned up in the archive at Ecbatana, one stone laid over the mouth of the lions' pit, one bag of silver handed to a servant.Ezr 6:2Dan 6:17Mat 25:15
Both pick a single member out of a named group, in the sense "one of them". Daniel steps up to one of the figures standing in his vision, and Judas is named as one of the Twelve.Dan 7:16Dan 6:2Mat 26:14
Both stand in where English expects "first" rather than "one". The Aramaic dates events to the first year of a king's reign, and the Greek dates the resurrection to the first day of the week.Ezr 5:13Dan 7:1Mat 28:1Mrk 16:2
Both can soften into something close to the English "a", introducing someone or something without any stress on the number: a letter sent to the king, a huge statue standing there, a scribe who came up to Jesus.Ezr 4:8Dan 2:31Mat 8:19Mat 9:18
Only the Greek word carries the confession that God himself is one. It is the word behind "the Lord is one", behind "there is one God", and behind the run of one Lord, one faith, one baptism. The Aramaic word never does this work in its handful of uses.Mrk 12:29Mrk 12:321Ti 2:5Eph 4:5Jas 2:19
Only the Greek word says that two who were separate have become a single whole. A husband and wife become "one flesh", the many parts add up to one body, and Jesus prays that his followers would be one the way he and the Father are one.Mat 19:5Eph 5:311Co 12:12Jhn 17:21
Only the Greek word is used to shut out every rival. There is one teacher and no other, one who is good, one lawgiver and judge. The point is not how many there are but that a second is ruled out.Mat 23:8Mat 19:17Mrk 10:18Jas 4:12
Only the Greek word is set against itself to sort two people or to turn the sense back on a group: one taken and one left, one master hated while the other is loved, a church told to build "one another" up.Mat 24:40Mat 6:241Th 5:11
What scholars say about ḥad
The lexica of Biblical Aramaic (HALOT's Aramaic volume, the BDB Aramaic section, and Vogt's Lexicon of Biblical Aramaic) treat חַד as the ordinary cardinal "one", cognate with Hebrew אֶחָד with loss of the initial aleph, and continuous with Old Aramaic, Syriac ḥad, and the later Jewish Aramaic dialects. The grammars of Biblical Aramaic (Rosenthal §46; Bauer and Leander) catalogue the extended constructions attested in Daniel and Ezra: the cardinal doing duty for the ordinal in regnal date formulae (Ezra 5:13; 6:3; Dan 7:1), the multiplicative חַד־שִׁבְעָה of Dan 3:19, the adverbial כַּחֲדָה "together" of Dan 2:35, and above all the incipient indefinite article, in which a postposed חַד approximates the function later fixed in Syriac and Jewish Aramaic. Commentators on Daniel (Montgomery in the ICC; Collins in Hermeneia) accordingly prefer "a great statue" at Dan 2:31 and "a stone" at Dan 6:17 over numerically weighted renderings, while noting that the numeral force is not everywhere spent: Dan 2:9 exploits it in the retort that the astrologers face one and the same verdict. The Aramaic of Ezra and Daniel is thus an early witness to a development that becomes standard in the later dialects, and no lexical uncertainty attaches to the word's core sense.
