'Once' in the Bible

For [it is] impossible [concerning] those who have once been enlightened, and have tasted the heavenly gift, and become sharers of the Holy Spirit,

who does not {need every day} like the former high priests to offer up sacrifices for his own sins [and] then for the [sins] of the people, because he did this once for all [when he] offered up himself.

but only the high priest [enters] into the second [tent] once a year, not without blood, which he offers on behalf of himself and the [sins] of the people committed in ignorance.

and not by the blood of goats and calves, but by his own blood, he entered once for all into the [most] holy place, obtaining eternal redemption.

since it would have been necessary for him to suffer many times from the foundation of the world, but now he has appeared once at the end of the ages for the removal of sin by the sacrifice of himself.

And {just as} it is destined for people to die once, and after this, judgment,

thus also Christ, having been offered once in order to bear the sins of many, will appear for the second time without reference to sin to those who eagerly await him for salvation.

For otherwise, would they not have ceased to be offered, because the ones who worship, having been purified once and for all, would no longer have any consciousness of sins?

by which will we are made holy through the offering of the body of Jesus Christ once for all.

whose voice shook the earth at that time, but now he has promised, saying, "Yet once [more] I will shake not only the earth but also heaven."

Now the [phrase] "yet once [more]" indicates the removal of what is shaken, namely, things that have been created, in order that the things that are not shaken may remain.
