Genesis 31:6-8, 41

You know that I have served your father with all my strength. Yet your father has cheated me and changed my wages ten times; however, God did not allow him to hurt me. If he spoke thus, ‘The speckled shall be your wages,’ then all the flock brought forth speckled; and if he spoke thus, ‘The striped shall be your wages,’ then all the flock brought forth striped.

These twenty years I have been in your house; I served you fourteen years for your two daughters and six years for your flock, and you changed my wages ten times.
