And he made there an altar, and there called upon the mighty God of Israel.

And he said, "I am that mighty God of thy father, fear not to go down into Egypt. For I will make of thee there a great people.

and yet his bow bode fast, and his arms and his hands were strong, by the hands of the mighty God of Jacob: out of him shall come a herdsman, a stone in Israel.
