'Keep' in the Bible

Indeed, we felt within ourselves that we had received the sentence of death [and were convinced that we would die, but this happened] so that we would not trust in ourselves, but in God who raises the dead.

so instead [of further rebuke, now] you should rather [graciously] forgive and comfort and encourage him, to keep him from being overwhelmed by excessive sorrow.

to keep Satan from taking advantage of us; for we are not ignorant of his schemes.

We, on the other hand, will not boast beyond our proper limit, but [will keep] within the limits of our commission (territory, authority) which God has granted to us as a measure, which reaches and includes even you.

And when I was with you and ran short [financially], I did not burden any of you; for what I needed was fully supplied by the brothers (Silas and Timothy) who came from Macedonia (the church at Philippi). So I kept myself from being a burden to you in any way, and will continue to do so.

Because of the surpassing greatness and extraordinary nature of the revelations [which I received from God], for this reason, to keep me from thinking of myself as important, a thorn in the flesh was given to me, a messenger of Satan, to torment and harass me—to keep me from exalting myself!
