Genesis 18:1-8 New Revised Standard Version (NRSV)
A Son Promised to Abraham and Sarah
18 The Lord appeared to Abraham[a] by the oaks[b] of Mamre, as he sat at the entrance of his tent in the heat of the day. 2 He looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground. 3 He said, “My lord, if I find favor with you, do not pass by your servant. 4 Let a little water be brought, and wash your feet, and rest yourselves under the tree. 5 Let me bring a little bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.” So they said, “Do as you have said.” 6 And Abraham hastened into the tent to Sarah, and said, “Make ready quickly three measures[c] of choice flour, knead it, and make cakes.” 7 Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it. 8 Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.
