Genesis 30:30-36

For you had little before I came and it has increased to a multitude, and the LORD has blessed you wherever I turned. But now, when shall I provide for my own household also?” So he said, “What shall I give you?” And Jacob said, “You shall not give me anything. If you will do this one thing for me, I will again pasture and keep your flock: let me pass through your entire flock today, removing from there every speckled and spotted sheep and every black one among the lambs and the spotted and speckled among the goats; and such shall be my wages. So my honesty will answer for me later, when you come concerning my wages. Every one that is not speckled and spotted among the goats and black among the lambs, if found with me, will be considered stolen.” Laban said, “Good, let it be according to your word.” So he removed on that day the striped and spotted male goats and all the speckled and spotted female goats, every one with white in it, and all the black ones among the sheep, and gave them into the care of his sons. And he put a distance of three days’ journey between himself and Jacob, and Jacob fed the rest of Laban’s flocks.
