'Herdsmen' in the Bible

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

And Abram said unto Lot, Let there be no strife, I pray thee, between me and thee, and between my herdsmen and thy herdsmen; for we are brethren.

And the herdsmen of Gerar strove with Isaac's herdsmen, saying, The water is ours. And he called the name of the well Esek, because they contended with him.
