Genesis 18:10-14

MLV(i) 10 And he said, I will certainly return to you when the season comes round, and behold, Sarah your wife will have a son. And Sarah heard in the tent door, which was behind him.
11 Now Abraham and Sarah were old and well stricken in age. It had ceased to be with Sarah after the manner of women. 12 And Sarah laughed within herself, saying, After I have become old shall I have pleasure from my lord who is also old?
13 And Jehovah said to Abraham, Why did Sarah laugh, saying, Shall I who am old certainly bear a child? 14 Is anything too hard for Jehovah? At the set time I will return to you, when the season comes round and Sarah will have a son.
