Charles Ellicott Commentary Joshua 10:31

"And Joshua passed from Libnah, and all Israel with him, unto Lachish, and encamped against it, and fought against it:" — Joshua 10:31 (ASV)

Lachish has been variously identified:

1. as Um-Lâkis;
2. Zukkanjek;
3. Tell-el-Hesy, near Eglon.

It cannot have been far from this latter place.
