Genesis 31:6-8, 41

And ye know that with all my power I have served your father. And your father hath deceived me, and changed my wages ten times; but God suffered him not to hurt me. If he said thus, The speckled shall be thy wages; then all the cattle bare speckled: and if he said thus, The ringstraked shall be thy hire; then bare all the cattle ringstraked.

Thus have I been twenty years in thy house; I served thee fourteen years for thy two daughters, and six years for thy cattle: and thou hast changed my wages ten times.
