Genesis 30:35; Genesis 30:39; Genesis 30:40

35 That same day he removed all the male goats that were streaked or spotted, and all the speckled or spotted female goats (all that had white on them) and all the dark-colored lambs, and he placed them in the care of his sons.

39 they mated in front of the branches. And they bore young that were streaked or speckled or spotted.

40 Jacob set apart the young of the flock by themselves, but made the rest face the streaked and dark-colored animals that belonged to Laban. Thus he made separate flocks for himself and did not put them with Laban’s animals.
