Genesis 26:20

And there was strife between the herdsmen of Abram’s livestock and the herdsmen of Lot’s livestock. Now the Canaanite and the Perizzite were living then in the land.

But Abraham reproved Abimelech about the well of water which the servants of Abimelech had seized.

then you shall say, ‘Your servants have been keepers of livestock from our youth and until now, both we and our fathers,’ that you may live in the land of Goshen; for every shepherd is an abomination to the Egyptians.”

He also built towers in the wilderness and hewed many cisterns, for he had much livestock, both in the Shephelah and in the plain. He also had plowmen and vinedressers in the hill country and the fertile fields, for he loved the soil.
