Genesis 30:27-32

But Laban said to him, “If now it pleases you, stay with me; I have divined that the LORD has blessed me on your account.” He continued, “Name me your wages, and I will give it.” But he said to him, “You yourself know how I have served you and how your cattle have fared with me. 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.
