John Gill 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)

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 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.
