'Once' in the Bible

But speaking of the time when He once more brings His Firstborn into the world, He says, "And let all God's angels worship Him."

For it is impossible, in the case of those who have once for all been enlightened, and have tasted the sweetness of the heavenly gift, and have been made partakers of the Holy Spirit,

who, unlike other High Priests, is not under the necessity of offering up sacrifices day after day, first for His own sins, and afterwards for those of the people; for this latter thing He did once for all when He offered up Himself.

and once for all entered the Holy place, taking with Him not the blood of goats and calves, but His own blood, and thus procuring eternal redemption for us.

In that case Christ would have needed to suffer many times, from the creation of the world onwards; but as a matter of fact He has appeared once for all, at the Close of the Ages, in order to do away with sin by the sacrifice of Himself.

And since it is reserved for all mankind once to die, and afterwards to be judged;

so the Christ also, having been once offered in sacrifice in order that He might bear the sins of many, will appear a second time, separated from sin, to those who are eagerly expecting Him, to make their salvation complete.

For then would not the sacrifices have ceased to be offered, because the consciences of the worshippers--who in that case would now have been cleansed once for all--would no longer be burdened with sins?

It is through that divine will that we have been set free from sin, through the offering of Jesus Christ as our sacrifice once for all.

let us draw near with sincerity and unfaltering faith, having had our hearts sprinkled, once for all, from consciences oppressed with sin, and our bodies bathed in pure water.

His voice then shook the earth, but now we have His promise, "Yet again I will, once for all, cause not only the earth to tremble, but Heaven also."

Here the words "Yet again, once for all" denote the removal of the things which can be shaken--created things--in order that the things which cannot be shaken may remain.
