Melech: a descendant of Saul, the second of the four sons of Micah in the family record of Saul's line; the name is spelled exactly like the everyday Hebrew word for "king"
The name turns up twice, and both times in the same short list. 1 Chronicles walks through the family of Saul in chapter 8 and then goes over much of it again in chapter 9, and in both places the sons of Micah are given as Pithon, Melech, Tarea, and Ahaz. The second copy of the list spells the third brother Tahrea, and the Hebrew there stops after three names, so English Bibles fill in Ahaz from the earlier list.
Micah's father was Merib-baal (מְרִיב בַּעַל), the man the book of Samuel calls Mephibosheth, and Merib-baal's father was Jonathan. That makes Melech a great-grandson of Jonathan and a great-great-grandson of Saul, born into the family that had lost the throne to David. He does nothing in the story. He is a name kept in a family record, and the record is the only reason we know he lived at all.
The name itself is simply the ordinary Hebrew word for a king (מֶלֶךְ). Israelite families built names out of that word freely, and usually said more with them than this one does:
- Malchi-shua (מַלְכִּישׁוּעַ), a son of Saul named a couple of verses earlier in the same record, means "my king is deliverance".
- Malchiah (מַלְכִּיָּהוּ) declares outright that the LORD is king.
- Malchiel (מַלְכִּיאֵל) says that God is his king.
- Malluch (מַלּוּךְ) is a short name from the same word with nothing added to it.
Bare "Melech" belongs with the last of those. It may be a shortened form of a longer name that honored God as king, or it may say no more than "King" and carry the memory of a family that had once held a throne. Two verses are not enough to settle it, and the shortest names are always the hardest to read.
One thing the surrounding list does show is that these old family names were kept as they stood. Saul's son Eshbaal and his grandson Merib-baal both carry the word for "lord" or "master" that the book of Samuel swaps out for the word for "shame", giving the more familiar Ish-bosheth and Mephibosheth. Here nothing was smoothed over, and a boy in a dethroned royal family could still be called King.
