'Back' in the Bible

So too, faith, if it does not have works [to back it up], is by itself dead [inoperative and ineffective].

Behold, the hire of the labourers who have reaped down your fields, which is of you kept back by fraud, crieth: and the cries of them which have reaped are entered into the ears of the Lord of sabaoth.

My brothers, if any among you strays from the truth, and someone turns 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.
