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.
