Genesis 18:1-10

1 The LORD appeared to Abraham by the oak trees belonging to Mamre as he was sitting at the entrance of his tent during the hottest part of the day.
2 Abraham looked up, and suddenly he saw three men standing near him. When he saw them, he ran to meet them, and he bowed with his face touching the ground.
3 "Please, sir," Abraham said, "stop by to visit me for a while.
4 Why don't we let someone bring a little water? After you wash your feet, you can stretch out and rest under the tree.
5 Let me bring some bread so that you can regain your strength. After that you can leave, since this is why you stopped by to visit me." They answered, "That's fine. Do as you say."
6 So Abraham hurried into the tent to find Sarah. "Quick," he said, "get three measures of flour, knead it, and make bread."
7 Then Abraham ran to the herd and took one of his best calves. He gave it to his servant, who prepared it quickly.
8 Abraham took cheese and milk, as well as the meat, and set these in front of them. Then he stood by them under the tree as they ate.
9 They asked him, "Where is your wife Sarah?" He answered, "Over there, in the tent."
10 The LORD said, "I promise I'll come back to you next year at this time, and your wife Sarah will have a son." Sarah happened to be listening at the entrance of the tent, which was behind him.
