Albert Barnes Commentary 2 Chronicles 25:12

"And [other] ten thousand did the children of Judah carry away alive, and brought them unto the top of the rock, and cast them down from the top of the rock, so that they all were broken in pieces." — 2 Chronicles 25:12 (ASV)

The top of the rock - Rather, “the height of Selah” (or, Petra), near which the battle was probably fought. On the cruel features of the Edomite wars, see 1 Kings 11:15; Ezekiel 25:12; Obadiah 1:14.
