'Back' in the Bible

Look! The wages that you kept back from the workers who harvested your fields are shouting out against you, and the cries of the reapers have reached the ears of the Lord of the Heavenly Armies.

My brothers, if one of you wanders away from the truth and somebody brings him back,

you may be sure that whoever brings a sinner back from his wrong path will save his soul from death and cover a multitude of sins.
