Genesis 13:5-8 (ESV)
5 And Lot, who went with Abram, also had flocks and herds and tents,
6 so that the land could not support both of them dwelling together; for their possessions were so great that they could not dwell together,
7 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.
8 Then Abram said to Lot, “Let there be no strife between you and me, and between your herdsmen and my herdsmen, for we are kinsmen.

19 Now the works of the flesh are evident: sexual immorality, impurity, sensuality,
20 idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,
21 envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God.
