Genesis 31:6

And ye know, that with all my power I have served your
father.
] With all faithfulness and uprightness; with all diligence and industry; with all wisdom and prudence; with all my might and main, contriving the best methods, and sparing no pains by day or night to take care of his flocks, and increase his substance: of this his wives had been witnesses for twenty years past, and to them he appeals for the truth of it; so that there was no just reason for their father's behaviour towards him.
