'Once' in the Bible

For concerning those who were once enlightened and tasted of the heavenly gift, and were made partakers of the Holy Spirit,

who doesn't need, like those high priests, to offer up sacrifices daily, first for his own sins, and then for the sins of the people. For he did this once for all, when he offered up himself.

but into the second the high priest alone, once in the year, not without blood, which he offers for himself, and for the errors of the people.

nor yet through the blood of goats and calves, but through his own blood, entered in once for all into the Holy Place, having obtained eternal redemption.

or else he must have suffered often since the foundation of the world. But now once at the end of the ages, he has been revealed to put away sin by the sacrifice of himself.

Inasmuch as it is appointed for men to die once, and after this, judgment,

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

Or else wouldn't they have ceased to be offered, because the worshippers, having been once cleansed, would have had no more consciousness of sins?

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

whose voice shook the earth then, but now he has promised, saying, "Yet once more I will shake not only the earth, but also the heavens."

This phrase, "Yet once more," signifies the removing of those things that are shaken, as of things that have been made, that those things which are not shaken may remain.
