26. And in the morning Jacob told his father Isaac the vow which he had vowed to the Lord, and the vision which he had seen, and that he had built an altar, 1 and that everything was ready for the sacrifice to be made before the Lord as he had vowed, and that he had come to set him on an ass. 27. And Isaac said unto Jacob his son: "I am not able to go with thee; for I am old, and not able to bear the way: go, my son, in peace; for I am one hundred and sixty-five years this day; I am no longer able to journey, set thy mother (on an ass) and let her go with thee. 28. And I know, my son, that thou hast come on my account, and may this day be blessed on which thou hast seen me alive, and I also have seen thee, my son. 29. Mayest thou prosper and fulfil the vow which thou hast vowed, and put not off thy vow; for thou wilt be called to account as touching the vow; 2 now therefore make haste to perform it, and may He be pleased who hath made all things, to whom thou hast vowed the vow." 30. And he said to Rebecca: "Go with Jacob thy son"; and Rebecca went with Jacob her son, and Deborah with her, and they came to Bethel. 31. And Jacob remembered the prayer with which his father had blessed him and his two sons, Levi and Judah, and he rejoiced and blessed the God of his fathers, Abraham and Isaac. 32. And he said: "Now I know that I have an eternal hope, and my sons also, before the God of all;" and thus is it ordained concerning the two; and they record it as an eternal testimony unto them on the heavenly tables how Isaac blessed them.
