And he said, I will give you a young goat from the flock. And she said, What will you give me as a sign till you send it? And he said, What would you have? And she said, Your ring and its cord and the stick in your hand. So he gave them to her and went in to her, and she became with child by him.

And he put questions to the men of the place, saying, Where is the loose woman who was in Enaim by the wayside? And they said, There was no such woman there. So he went back to Judah, and said, I have not seen her, and the men of the place say that there is no such woman there. And Judah said, Let her keep the things, so that we may not be shamed; I sent the young goat, but you did not see the woman.

But then he took his hand back again, and his brother came first to birth: and the woman said, What an opening you have made for yourself! So he was named Perez. And then his brother came out, with the red thread round his hand, and he was named Zerah.
