Genesis 30:32-33

30:32 Let me walk among all your flocks today and remove from them every speckled or spotted sheep, every dark-colored lamb, and the spotted or speckled goats. These animals will be my wages. 30:33 My integrity will testify for me later on. When you come to verify that I’ve taken only the wages we agreed on, if I have in my possession any goat that is not speckled or spotted or any sheep that is not dark-colored, it will be considered stolen.”

Genesis 30:35

30:35 So that day Laban removed the male goats that were streaked or spotted, all the female goats that were speckled or spotted (all that had any white on them), and all the dark-colored lambs, and put them in the care of his sons.

Genesis 30:40

30:40 Jacob removed these lambs, but he made the rest of the flock face the streaked and completely dark-colored animals in Laban’s flock. So he made separate flocks for himself and did not mix them with Laban’s flocks.
