Bible Verses About Servants: Called hireling

Is there not a warfare to man upon earth? And are not his days like the days of a hireling?

He that is a hireling, and not a shepherd, whose own the sheep are not, beholdeth the wolf coming, and leaveth the sheep, and fleeth, and the wolf snatcheth them, and scattereth them:

he fleeth because he is a hireling, and careth not for the sheep.
