quarry-cut stone: the cutting of stone out of rock, and so the ready blocks it supplies for building
This word turns up only three times, always inside the same fixed phrase, literally "stones of hewing," and always in a report about repairing the temple. In each case it names part of what the repair money bought: cut stone and timber, the two staples of any large building job in ancient Judah.
The phrase is trade language, not poetry. In 2 Kings 12:12 the same root shows up twice in one verse, once for the men who cut the stone and once for the stone they cut, which is exactly how a building account would talk. Hezekiah's tunnel workers used the same root of themselves in the inscription they carved at the end of their dig, so this was everyday vocabulary among rock-cutters. Phoenician building inscriptions use an almost identical phrase, which suggests a shared regional term for stone bought from the quarry works and delivered ready to lay.
Scholars disagree about which end of the process the word actually names:
- the work itself, so that the phrase reads "stones of cutting"
- the place where the cutting happens, that is, a quarry
- the finished block that comes out of the quarry
In practice the three readings arrive at the same translation, because the word never stands alone: it only ever describes stone. What it always signals is stone cut out of bedrock with tools and bought for a job, as opposed to loose stone (אֶבֶן) picked up off the ground, and as opposed to the smooth squared blocks (גָּזִית) used for altars and showpiece walls.
The heavy freight of this root lies elsewhere in the Bible: God as the quarryman who cut Israel out of rock, people hewing themselves leaky cisterns, prophetic words that hack like a pickaxe. All of that belongs to the verb (חָצַב), not to this noun. This is bookkeeping language, and its plainness is part of the point: a faithful king spends real money on real building stone to put God's house back in repair.
Disputed
Whether the noun names the action of hewing, the place where hewing is done (a quarry), or the hewn block itself.
- contestedA maqṭēl formation functioning as a nomen actionis, "hewing," so that אַבְנֵי מַחְצֵב is a construct chain meaning "stones of hewing," that is, hewn stones. On this analysis the noun is abstract and only characterizes the stone.; BDB, s.v. מַחְצֵב (p. 345a); TWOT §718a (Bruce K. Waltke)
- contestedA concrete maqṭēl noun, either a nomen loci ("quarry") or a nomen producti ("quarried stone"). The Phoenician noun מחצב and the compound ʾbn mḥṣb in construction inscriptions are the closest parallels, and the later Hebrew feminine formation מַחְצֵבָה ("quarry") points the same way.; HALOT, s.v. מַחְצֵב; Gesenius, Hebräisches und Aramäisches Handwörterbuch über das Alte Testament, 18. Auflage, ed. Rudolf Meyer and Herbert Donner, s.v. מַחְצֵב; DCH, ed. D. J. A. Clines, vol. 5, s.v. מַחְצֵב
