Genesis 13:14-18 (NIV)
14The Lord said to Abram after Lot had parted from him, "Lift up your eyes from where you are and look north and south, east and west.
15All the land that you see I will give to you and your offspring forever.
16I will make your offspring like the dust of the earth, so that if anyone could count the dust, then your offspring could be counted.
17Go, walk through the length and breadth of the land, for I am giving it to you."
18So Abram moved his tents and went to live near the great trees of Mamre at Hebron, where he built an altar to the Lord .
Genesis 18:1-15 (NIV)
1The Lord appeared to Abraham near the great trees of Mamre while he was sitting at the entrance to his tent in the heat of the day.
2Abraham looked up and saw three men standing nearby. When he saw them, he hurried from the entrance of his tent to meet them and bowed low to the ground.
3He said, "If I have found favor in your eyes, my lord, do not pass your servant by.
4Let a little water be brought, and then you may all wash your feet and rest under this tree.
5Let me get you something to eat, so you can be refreshed and then go on your way-now that you have come to your servant." "Very well," they answered, "do as you say."
6So Abraham hurried into the tent to Sarah. "Quick," he said, "get three seahs of fine flour and knead it and bake some bread."
7Then he ran to the herd and selected a choice, tender calf and gave it to a servant, who hurried to prepare it.
8He then brought some curds and milk and the calf that had been prepared, and set these before them. While they ate, he stood near them under a tree.
9"Where is your wife Sarah?" they asked him. "There, in the tent," he said.
10Then the Lord said, "I will surely return to you about this time next year, and Sarah your wife will have a son." Now Sarah was listening at the entrance to the tent, which was behind him.
11Abraham and Sarah were already old and well advanced in years, and Sarah was past the age of childbearing.
12So Sarah laughed to herself as she thought, "After I am worn out and my master is old, will I now have this pleasure?"
13Then the Lord said to Abraham, "Why did Sarah laugh and say, 'Will I really have a child, now that I am old?'
14Is anything too hard for the Lord ? I will return to you at the appointed time next year and Sarah will have a son."
15Sarah was afraid, so she lied and said, "I did not laugh." But he said, "Yes, you did laugh."
