'Defilement' in the Bible

So they brought Jesus from Caiaphas's house to the Praetorium. It was the early morning, and they would not enter the Praetorium themselves for fear of defilement, and in order that they might be able to eat the Passover.

Therefore, having these promises, beloved, let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God.

For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have contracted defilement make them holy so as to bring about ceremonial purity,

And, corresponding to that figure, the water of baptism now saves you--not the washing off of material defilement, but the craving of a good conscience after God--through the resurrection of Jesus Christ,

but chiefly them that walk after the flesh in the lust of defilement, and despise dominion. Daring, self-willed, they tremble not to rail at dignities:

They promise them liberty, when they themselves are the slaves of depravity—for by whatever anyone is defeated and overcome, to that [person, thing, philosophy, or concept] he is continually enslaved.

For if, after they have escaped the defilement of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in it and overcome, the last state has become worse for them than the first.
