'Contaminated' in the Bible

The Israelites are unable to stand before their enemies; they retreat because they have become subject to annihilation. I will no longer be with you, unless you destroy what has contaminated you.

Get up! Ritually consecrate the people and tell them this: 'Ritually consecrate yourselves for tomorrow, because the Lord God of Israel says, "You are contaminated, O Israel! You will not be able to stand before your enemies until you remove what is contaminating you."

I said, "Too bad for me! I am destroyed, for my lips are contaminated by sin, and I live among people whose lips are contaminated by sin. My eyes have seen the king, the Lord who commands armies."

For Samaria's disease is incurable. It has infected Judah; it has spread to the leadership of my people and has even contaminated Jerusalem!
