'Defilements' in the Bible

Remember them, my God, because of their defilements of the priesthood and the covenant of the priesthood and the Levites.

For if, [after they] have escaped from the defilements of the world through the knowledge of the Lord and Savior Jesus Christ, and they are again entangled in these [things] [and] succumb to [them], the last [state] has become worse for them than the first.
