Abraham and Isaac
Three visitors come to Abraham and say that he will have a son. Sarah believes she is too old to have a child and laughs. Yet she does conceive and in Genesis chapter 21: 1-7, Sarah has a baby named Isaac, which means laughter, just as the three visitors told her. Later, Abraham’s loyalty to Yahweh is tested when he is asked to give up Isaac as a sacrifice. The account in Genesis suggests that Abraham expected that Yahweh would give Isaac back to him somehow. A ram, caught in a thicket, is provided instead of Isaac.
