7 And Abraham ran to the herd, and brought a calf tender and good, and gave it to a young man; and he hasted 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 to him, Where is Sarah thy wife? And he said, Behold, in the tent.
10 And he said, I will certainly return to 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.
11 Now Abraham and Sarah were old and far advanced in age; and it ceased to be with Sarah after the manner of women.
12 Therefore Sarah laughed within herself, saying, After I am become old shall I have pleasure, my lord being old also?
13 And the LORD said to Abraham, Why did Sarah laugh, saying, Shall I certainly bear a child, who am old?
