When Judah saw her

The word "her" here refers to Tamar, but your reader should understand that Judah did not know that the woman he was looking at was Tamar.

because she had covered her face

Judah did not think she was a prostitute just because her face was covered but also because she was sitting in the gate. Alternate translation: "because she had covered her head and sat where prostitutes often sat" (See: rc://en/ta/man/jit/figs-explicit)
