Genesis 30:40

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

Geneva  Bible - And Jacob parted these lambs, and turned the faces of the flock towards those
lambs party colored, and all manner of black, among the sheep of Laban; so he
put his own flocks by themselves, and put them not with Laban’s flock
