On the very same day Abraham was circumcised, and Ishmael his son as well.
So Abram departed, as the Lord had directed him; and Lot [his nephew] went with him. Abram was seventy-five years old when he left Haran.
And Ishmael his son was thirteen years old when he was circumcised.
And all the men of his house, both those born in the house and those bought with money from a foreigner, were circumcised along with him.
I made haste and delayed not to keep Your commandments.
