'Polluted' in the Bible

but instead we should write to them to abstain from things polluted by idols, from sexual immorality, from eating anything that has been strangled, and from blood.

Crying out, Men of Israel, help: This is the man, that teacheth all men every where against the people, and the law, and this place: and further brought Greeks also into the temple, and hath polluted this holy place.
