Parallel
2 Chronicles 20:23
Jewish Publication Society 1917 · Berean Standard Bible
For the children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy them; and when they had made an end of the inhabitants of Seir, every one helped to destroy another.
The Ammonites and Moabites rose up against the inhabitants of Mount Seir, devoting them to destruction (note: Forms of the Hebrew cherem refer to the giving over of things or persons to the LORD, either by destroying them or by giving them as an offering.). And when they had finished off the inhabitants of Seir, they helped to destroy one another.
