Genesis 30:31-34

31Then he said, “What can I pay you?” Jacob said, “You don’t need to pay me anything. If you will do this one thing for me, I will shepherd your flock again and watch it:

32let me pass through your flock today, removing every colorfully spotted lamb from there and every dark-colored lamb among the sheep as well as the colorfully spotted among the goats—and that will be my salary.

33So tomorrow my honesty will testify on my behalf when you come to check on my salary you agreed to. Every one that isn’t colorfully spotted among the goats or dark-colored among the sheep with me, it is stolen.”

34So Laban said, “All right! May it be according to your word.”
