Genesis 18:1-15 (King James Version)
1And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
2And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
3And said, My LORD, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:
4Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
5And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.
6And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes upon the hearth.
7And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it.
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.
15Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.
