Gen 17:26 In the very same day Abraham was circumcised, and Ishmael his son.
Gen 18:1 Now the LORD appeared to him by the oaks of Mamre, while he was sitting at the tent door in the heat of the day.
Gen 18:2 When he lifted up his eyes and looked, behold, three men were standing opposite him; and when he saw them, he ran from the tent door to meet them and bowed himself to the earth,
Gen 18:3 and said, "My Lord, if now I have found favor in Your sight, please do not pass Your servant by.
Gen 18:4 "Please let a little water be brought and wash your feet, and rest yourselves under the tree;
Gen 18:5 and I will bring a piece of bread, that you may refresh yourselves; after that you may go on, since you have visited your servant." And they said, "So do, as you have said."
Gen 18:6 So Abraham hurried into the tent to Sarah, and said, "Quickly, prepare three measures of fine flour, knead it and make bread cakes."
Gen 18:7 Abraham also ran to the herd, and took a tender and choice calf and gave it to the servant, and he hurried to prepare it.
Gen 18:8 He took curds and milk and the calf which he had prepared, and placed it before them; and he was standing by them under the tree as they ate.
Gen 18:9 ¶ Then they said to him, "Where is Sarah your wife?" And he said, "There, in the tent."
Gen 18:10 He said, "I will surely return to you at this time next year; and behold, Sarah your wife will have a son." And Sarah was listening at the tent door, which was behind him.
Gen 18:11 Now Abraham and Sarah were old, advanced in age; Sarah was past childbearing.
Gen 18:12 Sarah laughed to herself, saying, "After I have become old, shall I have pleasure, my lord being old also?"
Gen 18:13 And the LORD said to Abraham, "Why did Sarah laugh, saying, 'Shall I indeed bear a child, when I am so old?'
Gen 18:14 "Is anything too difficult for the LORD? At the appointed time I will return to you, at this time next year, and Sarah will have a son."
Gen 18:15 Sarah denied it however, saying, "I did not laugh"; for she was afraid. And He said, "No, but you did laugh."
Gen 18:16 ¶ Then the men rose up from there, and looked down toward Sodom; and Abraham was walking with them to send them off.
Gen 18:17 The LORD said, "Shall I hide from Abraham what I am about to do,
Gen 18:18 since Abraham will surely become a great and mighty nation, and in him all the nations of the earth will be blessed?
Gen 18:19 "For I have chosen him, so that he may command his children and his household after him to keep the way of the LORD by doing righteousness and justice, so that the LORD may bring upon Abraham what He has spoken about him."
