Genesis 30:30-36

For you had little before I came and it has increased and multiplied abundantly, and the LORD has favored you with blessings wherever I turned. But now, when shall I provide for my own household?” Laban asked, “What shall I give you?” Jacob replied, “You shall not give me anything. But if you will do this one thing for me [which I now propose], I will again pasture and keep your flock: Let me pass through your entire flock today, removing from it every speckled and spotted sheep and every dark or black one among the lambs and the spotted and speckled among the goats; and those shall be my wages. So my honesty will be evident for me later, when you come [for an accounting] concerning my wages. Every one that is not speckled and spotted among the goats and dark among the young lambs, if found with me, shall be considered stolen.” And Laban said, “Good! Let it be done as you say.” So on that same day Laban [secretly] removed the male goats that were streaked and spotted and all the female goats that were speckled and spotted, every one with white on it, and all the dark ones among the sheep, and put them in the care of his sons. And he put [a distance of] three days’ journey between himself and Jacob, and Jacob was then left in care of the rest of Laban’s flock.
