Charles Ellicott Commentary Genesis 38:5

"And she yet again bare a son, and called his name Shelah: and he was at Chezib, when she bare him." — Genesis 38:5 (ASV)

Chezib. —Mr. Conder has found traces of this place at Ain Kezbeh, near Beit Nettif, a little to the north of Adullam (Handbook, p. 408). In Micah 1:14-15, it is called Achzib, and is there also placed near Adullam.
