Genesis 30:40

Jacob set apart the young, but made the rest face the streaked dark-colored sheep in Laban’s flocks. Then he set his own stock apart and did not put them with Laban’s animals.

And Jacob did separate the lambs, and set the faces of the flocks toward the ringstraked, and all the brown in the flock of Laban; and he put his own flocks by themselves, and put them not unto Laban’s cattle.
