Genesis 31:38

This twenty years [have] I been [with] thee
So that he now must have been ninety seven years of age: thy ewes and thy she goats have not cast their young:
or very few of them: it was a rare case for any to be abortive, if ever: this, though owing to the blessing of God, was for Jacob's sake, and, under God, to be ascribed to his care and diligence in watching and keeping the flock, and doing everything needful for them: and the rams of the flock have I not eaten:
being content with meaner food, as lentil pottage and the like; see the contrary of this in shepherds, ( Ezekiel 34:3 ) .
