So Abram went up from Egypt, he and his wife and all that he had, and Lot with him, into the Negeb. Now Abram was very rich in livestock, in silver, and in gold. And he journeyed on from the Negeb as far as Bethel to the place where his tent had been at the beginning, between Bethel and Ai, to the place where he had made an altar at the first. And there Abram called upon the name of the Lord. And Lot, who went with Abram, also had flocks and herds and tents, so that the land could not support both of them dwelling together; for their possessions were so great that they could not dwell together, and there was strife between the herdsmen of Abram's livestock and the herdsmen of Lot's livestock. At that time the Canaanites and the Perizzites were dwelling in the land. – Genesis 13:1-7

Though it should be assumed that Abram was a rich man before his encounter in Egypt, it is worth noting that the reference comes after the encounter. This same reflection sets the stage for the wealth that Israel would take out of Egypt during the Exodus (Exo 12:33-36) and even the much later exodus from Babylon (Ezra 1:5-6). These blessing in fact cause a unbearable burden that sets up the next set of important developments for Abram and Lot.

Upon returning to the first alter Abram again petition himself before the Lord. This works to demonstrate that “all who calls on the name of the Lord shall be saved” (Joel 2:28-32; Acts 2:21; Rom 10:13).
