7 And Abraham ran unto the herd and brought a calf tender and good and gave it unto a young man; and he hastened to dress it.
8 And 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 ate.
9 And they said unto him, Where is Sarah thy wife? And he said, Here, in the tent.
10 Then he said, I will certainly return unto thee according to the time of life; and, behold, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him.
11 Now Abraham and Sarah were old and well stricken in age, and it ceased to be with Sarah after the manner of women.
12 Therefore Sarah laughed within herself, saying, After I am waxed old, shall I have pleasure, my lord being old also?
13 Then the Lord said unto Abraham, Why did Sarah laugh, saying, Shall I of a surety bear a child when I am old?
