Genesis 13:7

And there was a strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle: and the Canaanite and the Perizzite dwelled then in the land.

And there was a strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle,.... Not between the two masters, but between their servants, their upper servants, that had the care of their herds to feed them, and water them; and it is very probable their strife was about pasturage and watering places, the one endeavouring to get them from the other, or to get the best; which is much more likely than what Jarchi suggests, that the herdmen of Lot were wicked men, and fed their cattle in the fields of others, and the herdmen of Abram reproved them for their robbery; but they said, the land is given of Abram, and he hath no heir, but Lot is his heir, and what robbery is this? and to this sense are the Targums of Jonathan and Jerusalem:

and the Canaanite and the Perizzite dwelt then in the land; which observation is made by Moses to point to a reason why they could not both of them have a sufficiency for their large flocks and herds, because the country was in the possession of others; and though there was to spare, yet not enough for them both. The Canaanite, though it was a general name for the people of the whole land, yet was given to a particular family in it, and was derived from their first founder Canaan, the son of Ham; the Perizzite was another family or tribe of the same nation, who had their name from zwrp, "a village"; these being Pagans or villagers, living in huts, or houses, or tents scattered up and down in the fields, and were a rough, inhuman, and unsociable sort of people, and therefore it could not be expected that they would oblige them with much pasturage and water for their flocks: and besides, this may be remarked, partly to show the danger that Abram and Lot were in through the dissension of their herdmen, since those people that were so nigh might take the advantage of their quarrels among themselves, and fall upon them both, and destroy them, and therefore a reconciliation was necessary; and partly to observe the reproach that was like to come upon them, and upon the true religion, for their sakes, should they differ among themselves, which such sort of men would gladly catch at, and improve against them.
