'Defiled' in the Bible

I know Ephraim, and Israel is not hid from me: for now, O Ephraim, thou committest whoredom, and Israel is defiled.

I have seen an horrible thing in the house of Israel: there is the whoredom of Ephraim, Israel is defiled.

They will not pour outtheir wine offerings to the Lord,and their sacrifices will not please Him.Their food will be like the bread of mourners;all who eat it become defiled.For their bread will be for their appetites alone;it will not enter the house of the Lord.
