Genesis 38:5

And she yet again conceived, and bare a son; and called his name Shelah: and he was at Chezib, when she bare him.

And she conceived, and bare a son,.... A third son:

and called his name Shelah; which signifies tranquil, quiet, peaceable and prosperous, and is a word that comes from the same root as Shiloh, that famous son of Judah that should spring from him, Genesis 49:10 the reason of the name, as given by the Targum, is,

"because her husband forgot her:''

and she was at Chezib when she bare him; Chezib is the name of a place, by some taken to be the same with Achzib or Ecdippe, now Zib, see Micah 1:14; it seems to be a city in the tribe of Judah; and Jerom {n} says, in his time there was a desert place of this name near Adullam, on the borders of Eleutheropolis; the reason of her being here at the time of her delivery, and of this circumstance being related, is not certain.
