Charles Ellicott Commentary Genesis 38:14

"And she put off from her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of Enaim, which is by the way to Timnah; for she saw that Shelah was grown up, and she was not given unto him to wife." — Genesis 38:14 (ASV)

In an open place. —Hebrew, in the gate of Enajim. Enajim means “the two fountains,” and we learn from Genesis 38:21 that it was the town where Tamar’s father lived, and where Tamar was living with him in her widowhood. In the exploration of Palestine, Enajim has been identified with a place called Allin, Anin, or Anaim, three miles east of Tibneh, and situated on an ancient road coming from Adullam. This makes the conclusion, reached for other reasons, certain, that the Timnath on the Philistine border was the town meant.
