Parallel
2 Samuel 12:31
Brenton's English Septuagint · Berean Standard Bible
And he brought forth the people that were in it, and put them under the saw, and under iron harrows, and axes of iron, and made them pass through the brick-kiln: and thus he did to all the cities of the children of Ammon. And David and all the people returned to Jerusalem.
David brought out the people who were there and put them to work with saws (note: Literally put them under saws), iron picks, and axes, and he made them work at the brick kilns (note: Literally and he made them pass through the brick kilns.). He did the same to all the Ammonite cities. Then David and all his troops returned to Jerusalem.
