Genesis 18:5-15

5 And I will bring a morsel of bread, and comfort ye your hearts; after that you shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.
6 And Abraham hastened into the tent to Sarah, and said, Make ready quickly three measures of fine meal, knead [it], and make cakes upon the hearth.
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?
14 Is any thing too hard for the LORD? At the time appointed I will return to thee, according to the time of life, and Sarah shall have a son.
15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.
