'Hireling' in the Bible

It shall not seem hard to you, when you let him go free from you; for to the double of the hire of a hireling has he served you six years: and Yahweh your God will bless you in all that you do.

As a servant who earnestly desires the shadow, as a hireling who looks for his wages,

Look away from him, that he may rest, until he shall accomplish, as a hireling, his day.

I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against the perjurers, and against those who oppress the hireling in his wages, the widow, and the fatherless, and who deprive the foreigner of justice, and don't fear me," says Yahweh of Armies.
