'Second' in the Bible

And behind the second veil was a sacred tent called the Holy of holies.

But into the second, the High Priest goes only on one day of the year, and goes alone, taking with him blood, which he offers on his own behalf and on account of the sins which the people have ignorantly committed.

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.

He then adds, "I have come to do Thy will." He does away with the first in order to establish the second.
