'Purified' in the Bible

Indeed, nearly everything is purified with blood according to the law, and apart from the shedding of blood there is no forgiveness.

Therefore [it was] necessary [for] the sketches of the [things] in heaven to be purified with these [sacrifices], but the heavenly [things] themselves [to be purified] with better sacrifices than these.

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?
