Charles Ellicott Commentary 2 Chronicles 20:24

"And when Judah came to the watch-tower of the wilderness, they looked upon the multitude; and, behold, they were dead bodies fallen to the earth, and there were none that escaped." — 2 Chronicles 20:24 (ASV)

And when Judah came. — Now Judah had come; by the time the slaughter was complete.

Toward the watch tower. — The look-out of the desert. A height overlooking the wilderness of Jeruel (2 Chronicles 20:16). The word mizpeh means watch-tower in Isaiah 21:8.

They looked. — And they looked.

Behold, they were dead bodies. — Compare to 2 Kings 19:35.

None escaped. — No survivors were anywhere visible. Vulgate: “Porro Juda cum venisset ad speculam quae respicit solitudinem vidit procul ... nec superesse quemquam qui necem potuisset evadere.”
