Genesis 30:32-35

32Do this: Let me go among all your animals today. Let me remove any animal that has a mark on it or that has more than one colour on its skin. I will also take any black lambs. That is what you will give me for my work.

33In the future, this will show that I am honest. You can check on my animals whenever you want to. I will only have sheep or goats that have marks on their skin, or black lambs. If I have any other animals, you may call me a robber.’

34Laban said, ‘I agree to this. It will be as you have said.’

35On that same day, Laban went to his animals. He quickly removed all the goats that had marks, both male and female goats. He also removed all the black lambs. He gave these animals to his sons to take care of them.
