Midrash su Genesi 38:13

It is written (Judges 14, 1) And Samson went down to Timnata. Again it is written (Gen. 38, 13) Behold thy father-in-law goeth up to Timnata to sheer his sheep. [How do up and down correspond?] Said R. Elazar, "Samson disgraced himself with that journey, therefore it is written that he went down, but Juda became elevated through that journey, therefore it is written that he goeth up." R. Samuel, the son of R. Nachmeni explained that there were two cities called Timnata; one was down-hill the other was up-hill. R. Papa said: "It is one and the same Timnata only [it was situated on the slope of a hill]. Then one came from one side, he had to descend to it and the one that came from the other side to ascend the hill, similar to Vardina, Be-barei and the market place of Narash." Ib., ib. 14) And seated herself at the cross-road. Said R. Alexandria: "From this we infer that she went and occupied a seat at the door where Abraham's house was situated, a place where many eyes could see her." R. Jochanan said: "A place the name of which was Enaim, and such a name we find (Josh. 15, 34) Thappuach, and Enaim."

What is written above on the matter (in Gen. 38:13-14)? AND IT WAS TOLD TO TAMAR, SAYING: < HERE IS YOUR FATHER-IN-LAW COMING >…. SO SHE PUT HER WIDOW'S CLOTHES OFF [FROM HER] AND COVERED HERSELF WITH A VEIL. < THEN, HAVING WRAPPED HERSELF, SHE SAT DOWN AT THE ENTRANCE TO ENAIM >. Two women covered themselves with a veil and bore twins. These are Rebekah and Tamar.⁵³Gen. R. 60:15; 85:7. Of Rebekah it is written (in Gen. 24:65): SO SHE TOOK THE VEIL AND COVERED HERSELF. Then she bore twins, Esau and Jacob, as stated (in Gen. 25:24): BEHOLD, THERE WERE TWINS IN HER WOMB. As for Tamar, she covered herself with a veil and (according to Gen. 38:27-30) bore twins, Perez and Zerah.
