'Defiled' in the Bible

I know Ephraim, and Israel is not hidden from Me;For now, O Ephraim, you have played the harlot,Israel has defiled itself.

In the house of Israel I have seen a horrible thing;Ephraim’s harlotry is there, Israel has defiled itself.

They will not pour out drink offerings of wine to the Lord,Their sacrifices will not please Him.Their bread will be like mourners’ bread;All who eat of it will be defiled,For their bread will be for themselves alone;It will not enter the house of the Lord.
