a cut: a piece sliced off, such as a cheese, or a sharp iron tool used for cutting
This is a rare word, appearing only three times, and it is always concrete. Underneath its two uses lies one simple idea: something to do with cutting. In one place it is a slice cut from pressed milk-curds, that is, a cheese. In the other two it is a sharp iron tool, listed alongside saws and axes. The same noun fits both because both are, quite literally, a cut: one is the piece that has been cut off, the other is the blade that does the cutting.
Because the word standing next to it fixes the sense, a reader is rarely in doubt. "Cuts of milk" gives cheeses; "cuts of iron" gives cutting tools. What ties the uses together is the plain physical act of cutting, with no special or religious weight added.
Nuances
Whether 2 Samuel 12:31 reports that David subjected the captured Ammonites to forced labor with saws and iron implements or executed them with those implements. The debate turns on the governing verb (Masoretic wayyasem, "he set them to," versus the harsher parallel wayyasar in 1 Chronicles 20:3, traditionally taken as "he sawed them"), not on the meaning of the iron tools.
- majorityDavid consigned the captured population to forced labor and demolition work with saws, iron implements, and axes; the tools are the equipment they were set to work with. This follows the plain Hebrew construction "he set them to" plus the concurring Septuagint, Peshitta, and Targum.; P. Kyle McCarter Jr., II Samuel (Anchor Bible 9, 1984), on 12:26-31; David Toshio Tsumura, The Second Book of Samuel (NICOT, 2019), on 12:31; A. A. Anderson, 2 Samuel (Word Biblical Commentary 11, 1989), on 12:31; Robert Alter, The David Story (1999), on 2 Samuel 12:31; Septuagint (2 Kingdoms) 12:31
- minorityDavid executed the captives, cutting them with the saws and iron implements. This reading rests on the harsher parallel verb in 1 Chronicles 20:3 ("he cut/sawed them") and on the Latin Vulgate's serravit ("he sawed").; C. F. Keil and F. Delitzsch, Biblical Commentary on the Books of Samuel, on 12:31; Vulgate, 2 Samuel 12:31 (serravit)
