Genesis 30:31-34

31“What can I give you?” Laban asked.

“You do not need to give me anything,” Jacob replied. “If you do this one thing for me, I will keep on shepherding and keeping your flocks. 32Let me go through all your flocks today and remove from them every speckled or spotted sheep, every dark-colored lamb, and every spotted or speckled goat. These will be my wages. 33So my honesty will testify for me when you come to check on my wages in the future. If I have any goats that are not speckled or spotted, or any lambs that are not dark-colored, they will be considered stolen.”

34“Agreed,” said Laban. “Let it be as you have said.”
