Ezekiel 4:13

And the Lord said, even thus shall the children of Israel,
&c.] Not the ten tribes only, or those who were among the other two, but all the Jews in captivity: eat the defiled bread among the Gentiles, whither I will drive them;
so called, not because mixed, but baked in the above manner; which was a symbol of the defilements which they should contract upon various accounts, by dwelling among the Gentiles; so that this foretells their captivity; their pollution among the nations of the world; and that they should not be the holy people to the Lord they had been, and had boasted of. The Jews ^F11 cite this passage to prove that he that eats bread without drying his hands is as if he ate defiled bread.
