μισθωτός

But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.

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

And straightway he called them: and they left their father Zebedee in the ship with the hired servants, and went after him.
