'Once' in the Bible

For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit,

who does not need daily, like those high priests, to offer up sacrifices, first for His own sins and then for the sins of the people, because this He did once for all when He offered up Himself.

but into the second, only the high priest enters once a year, not without taking blood, which he offers for himself and for the sins of the people committed in ignorance.

and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption.

Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been manifested to put away sin by the sacrifice of Himself.

And inasmuch as it is appointed for men to die once and after this comes judgment,

so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him.

Otherwise, would they not have ceased to be offered, because the worshipers, having once been cleansed, would no longer have had consciousness of sins?

By this will we have been sanctified through the offering of the body of Jesus Christ once for all.

And His voice shook the earth then, but now He has promised, saying, “Yet once more I will shake not only the earth, but also the heaven.”

This expression, “Yet once more,” denotes the removing of those things which can be shaken, as of created things, so that those things which cannot be shaken may remain.
