We read ch 22, Abraham dwelt in Beersheva. And he hears of his brother Nahor had 12 children listed from milkah and 1 of his concubine. Then to ch 23 we here Abraham goes to morn Sarah in Hebron. That's appx 43 miles away, then went North to Mamre, land where the Hittites lived. Descendants of Heth, son of Canaan, who was the son of Ham. In the land of Canaan. We know Isaac lived near Kadash south of Beersheva for a bit. When did Abraham pack up and move to Hebron?
Genesis 13:14-13:18 14 After 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 15 all the land that you see I will give to you and your descendants forever. 16 I 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. 17 Get up and walk through the land, across its length and breadth, for I give it to you. 18 Abram 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.
