'Polluted' in the Bible

Gilead is a city of them that work iniquity, and is polluted with blood.

A day of our king! Princes have polluted themselves with the poison of wine, He hath drawn out his hand with scorners.

They shall not offer wine offerings to the LORD, neither shall they be pleasing unto him: their sacrifices shall be unto them as the bread of mourners; all that eat thereof shall be polluted: for their bread for their soul shall not come into the house of the LORD.
