'Year' in the Bible

But the high priest alone enters the second room, and he does that only once a year, and never without blood, which he offers for himself and for the sins of the people committed in ignorance.

Since the law has only a shadow of the good things to come, and not the actual form of those realities, it can never perfect the worshipers by the same sacrifices they continually offer year after year.

But in the sacrifices there is a reminder of sins every year.
