'Heathen' in the Bible

Then Ezra the priest stood up and said to them, “You have been unfaithful [to God] and have married foreign (pagan) women, adding to the guilt of Israel.

So now, make confession to the Lord God of your fathers and do His will. Separate yourselves from the peoples of the land and from [your] foreign wives.”

They vowed to send away their [pagan] wives, and being guilty, they each offered a ram of the flock for their offense.
