And the Lord appeared unto him in the Plains of Mamre; and he sat in the tent door in the heat of the day, and he lifted up his eyes and looked and lo, 3 men stood by him; and when he saw them, he ran to meet them from the tent door,
and bowed himself toward the ground and said my Lord if now I have found favour in the sight, pass not away; I pray thee, from thy servant: let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree; and I will fetch a morsel of bread, and comfort your heart after that Ye shall pass on;
therefore are you come to your servant. and they said, so do as thou has said. And Abraham hastened into the tent unto Sarah, and said make ready quickly 3 measures of fine meal, knead it, and make cakes upon the hearth. And Abraham ran into the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it. And he took butter, and milk, and the calf which he had dressed, and sat it before them ;and he stood by them under the tree, and they did eat .And they said unto him, where is Sarah the why and he said behold in the tent and he said I will certainly return into the according to the time of life and lo Sarah the wife ? And he said, behold, in the tent. And 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, Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women, therefore Sarah laughed within herself, saying after I am waxed old shall I have pleasure, my Lord been old also?
And the Lord said unto Abraham wherefore did Sarah laugh, saying,Shall I of a surety bear a child ,which am old ?is 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.
