Genesis 38:15 Meaning and Commentary

Genesis 38:15

When Judah saw her, he thought her [to be] an harlot
By her posture and the place she was in: because she had covered her face;
with her veil, that he did not know her; for this is not given as a reason why he took her to be an harlot; the reason of this was, because she sat in the public road; but having covered her face he could not discern who she was, and therefore, from the other circumstance, concluded that she was an harlot, and sat there to prostitute herself to any that passed by.

Genesis 38:15 In-Context

13 It was told Tamar, saying, "Behold, your father-in-law is going up to Timnah to shear his sheep."
14 She took off of her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of `Enayim, which is by the way to Timnah; for she saw that Shelach was grown up, and she wasn't given to him as a wife.
15 When Yehudah saw her, he thought that she was a prostitute, for she had covered her face.
16 He turned to her by the way, and said, "Please come, let me come in to you:" for he didn't know that she was his daughter-in-law. She said, "What will you give me, that you may come in to me?"
17 He said, "I will send you a kid of the goats from the flock." She said, "Will you give me a pledge, until you send it?"
