'Defiled' in the Bible

I myself know Ephraim, and Israel is not hidden from me; because now you have played the whore, Ephraim-- Israel is defiled.

In the house of Israel I have seen something horrible; Ephraim's unfaithfulness [is] there. Israel is defiled.

They will not pour [drink offerings of] wine to Yahweh, and their sacrifices will not please him. [They are] like mourners' bread for them; all those who eat it will be defiled. For their bread will be {for their hunger}; it will not come [to] the house of Yahweh.
