Bereshis 17:21-23

Orthodox Jewish Bible

²¹ But My Brit (covenant) will I establish with Yitzchak, which Sarah shall bear unto thee at mo’ed hazeh (this set time) next year.

²² And He left off speaking with him, and Elohim went up from Avraham.

²³ And Avraham took Yishmael bno, and all that were born in his bais, and all that were bought with his kesef, every zachar among the men of Avraham’s bais; and circumcised the basar of their arelah in the very same day, as Elohim had said unto him.
