Gn 13:14-18

14After Lot had parted from him, the LORD said to Abram: Look about you, and from where you are, gaze to the north and south, east and west;^e 15all the land that you see I will give to you and your descendants forever.^f 16I will make your descendants like the dust of the earth; if anyone could count the dust of the earth, your descendants too might be counted.^g 17Get up and walk through the land, across its length and breadth, for I give it to you. 18Abram moved his tents and went on to settle near the oak of Mamre, which is at Hebron. There he built an altar to the LORD.^h
