Genesis 30:31-36

So he said, “What shall I give you?” And Jacob said, “You shall not give me anything. If you will do this thing for me, I will again feed and keep your flocks: Let me pass through all your flock today, removing from there all the speckled and spotted sheep, and all the brown ones among the lambs, and the spotted and speckled among the goats; and these shall be my wages. So my righteousness will answer for me in time to come, when the subject of my wages comes before you: every one that is not speckled and spotted among the goats, and brown among the lambs, will be considered stolen, if it is with me.” And Laban said, “Oh, that it were according to your word!” So he removed that day the male goats that were speckled and spotted, all the female goats that were speckled and spotted, every one that had some white in it, and all the brown ones among the lambs, and gave them into the hand of his sons. Then he put three days’ journey between himself and Jacob, and Jacob fed the rest of Laban’s flocks.
