8And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat. 9And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent. 10And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him. 11Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women.12Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also? 13And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old? 14Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.
