'Pollute' in the Bible

So you shall not pollute and defile the land in which you live; for [the shedding of innocent] blood pollutes and defiles the land. No atonement (expiation) can be made for the land for the [innocent] blood shed in it, except by the blood (execution) of him who shed it.

and I pronounced them unclean because of their offerings [to their idols], in that they made all their firstborn pass through the fire [as pagan sacrifices], so that I might make them desolate, in order that they might know [without any doubt] that I am the Lord.”’

In that you brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in My sanctuary to pollute and profane it—My house—when you offered My bread, the fat, and the blood; and they made My covenant void —this in addition to all your other repulsive acts.

Armed forces of his will arise [in Jerusalem] and defile and desecrate the sanctuary, the [spiritual] stronghold, and will do away with the regular sacrifice [that is, the daily burnt offering]; and they will set up [a pagan altar in the sanctuary which is] the abomination of desolation.

there is nothing outside a man [such as food] which by going into him can defile him [morally or spiritually]; but the things which come out of [the heart of] a man are what defile and dishonor him.
