What does Genesis 13:7 mean?
God had blessed Abram and Lot abundantly, including in the size of their herds of livestock. According to this verse, that growth has gotten to the point where their herdsmen were quarreling over resources. Even the most fertile land can only support so many livestock and people. One can imagine herdsmen from either family trying to graze and water their flocks in the same areas, fighting over the right to those fields. Once Lot and Abram's combined tribes became large enough, the only real option was to split up to prevent stagnation.Though there was room to spread out in the area around Bethel, the land was not empty. This verse reminds us that it was occupied both by the Canaanites and a people group called the Perizzites. This is part of the land God has promised to Abram's descendants (Genesis 12:7), but for the time being, it is under the control of a different culture.
