13 And when they were committing iniquity before thee, thou didst choose for thyself one of them, whose name was Abraham;

14 and thou didst love him, and to him only didst thou reveal the end of the times, secretly by night.

15 Thou didst make with him an everlasting covenant, and promise him that thou wouldst never forsake his descendants; and thou gavest to him Isaac, and to Isaac thou gavest Jacob and Esau.

16 And thou didst set apart Jacob for thyself, but Esau thou didst reject; and Jacob became a great multitude.

17 And when thou didst lead his descendants out of Egypt, thou didst bring them to Mount Sinai.
