Genesis 13:6-8

Young's Literal Translation

⁶ and the land hath not suffered them to dwell together, for their substance hath been much, and they have not been able to dwell together;

⁷ and there is a strife between those feeding Abram's cattle and those feeding Lot's cattle; and the Canaanite and the Perizzite [are] then dwelling in the land.

⁸ And Abram saith unto Lot, `Let there not, I pray thee, be strife between me and thee, and between my shepherds and thy shepherds, for we [are] men -- brethren.
