One of the guests was the LORD, and he said, "I'll come back about this time next year, and when I do, Sarah will already have a son." Sarah was behind Abraham, listening at the entrance to the tent.
Jacob packed up everything he owned and left for Egypt. On the way he stopped near the town of Beersheba and offered sacrifices to the God his father Isaac had worshiped.
Because Abraham had faith, he lived as a stranger in the promised land. He lived there in a tent, and so did Isaac and Jacob, who were later given the same promise.
