Gênesis 17:25

Gen 17:25 And Ishmael his son [was] thirteen years old, when he was circumcised in the flesh of his foreskin.

Ver. 25. And Ishmael his son was thirteen years old. ] The Turks’ children are not circumcised till they are ten years old, and then they use great feasting, banqueting, music, and bringing of presents. a They say that Abraham loved Ishmael, and not Isaac: and that it was Ishmael whom Abraham would have sacrificed.
