And God said—Truly, Sarah thy wife, is about to bear thee a son, and thou shalt call his name, Isaac,—and I will establish my covenant with him as an age-abiding covenant, to his seed after him.
And he gave unto him a covenant of circumcision; and, thus, he begat Isaac, and circumcised him on the eighth day, and Isaac, Jacob, and Jacob, the twelve patriarchs.
And he said—Take, I pray thee, thy son, thine only one, whom thou lovest, even, Isaac, and get thee into the land of Moriah and cause him to ascend there as an ascending-sacrifice, on one of the mountains which I shall name unto thee.
And God said unto Abraham Let it not be grievous in thine eyes concerning the boy and concerning thy bondwoman, In all that Sarah may say unto thee, hearken to her voice,—For in Isaac, shall there be called to thee—a seed.
