Since this part of Scripture is mainly in narrative form, it is helpful to briefly consider the plot. The story can be divided in three parts as follows:
Genesis 13:1–5 introduces us to the situation or the setting, where we see Abram and Lot as some sort of nomads, travelling from place to place. They are in possession of great wealth, especially in terms of livestock. It also records one of Abram’s typical worship acts at the altars he had built earlier on, to the Lord.
Genesis 13:6–13 presents the tension between Abram and Lot’s herdsmen. This is caused by the competition among their herdsmen for grazing area. This tension is solved through a suggestion made by Abram to part ways with Lot.
Genesis 13:14–18 presents the Lord’s oracle after the ordeal of the separation. This section is concluded by Abram’s worship to the Lord.1
1 So Abram went up from Egypt, he and his wife and all that he had, and Lot with him, into the Negeb.
