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 When Tamar was told, "Your father-in-law is going up to Timnah to shear his sheep,"
14 she put off her widow's garments, put on a veil, wrapped herself up, and sat down at the entrance to Enaim, which is on the road to Timnah. She saw that Shelah was grown up, yet she had not been given to him in marriage.
15 When Judah saw her, he thought her to be a prostitute, for she had covered her face.
16 He went over to her at the roadside, and said, "Come, let me come in to you," for he did not know that she was his daughter-in-law. She said, "What will you give me, that you may come in to me?"
17 He answered, "I will send you a kid from the flock." And she said, "Only if you give me a pledge, until you send it."
