When Judah saw her, he thought her to be a harlot; because she had covered her face.
Read Chapter 38
Ephrem The Syrian
While Tamar was making supplication to God for these things, behold, Judah came out and saw her. The prayer of Tamar inclined him, contrary to his usual habit, [to go] to a harlot. When she saw him, she was veiled, for she was afraid. After the word of the sign for which she had asked had been spoken, she knew that God was pleased with what she was doing. Afterward she revealed her face without fear and even demanded remuneration from the lord of the treasure.
