Canaan, the land of Jehovah, is holy, Assyria unholy (Amos 7:17), where there was no temple or sacred ordinances. Since meat was not a divinely sanctioned food, except in connection with a Jehovah festival, it became in the land of exile unclean. This became true in the eyes of Hosea of all eating. “In the family every feast was a Eucharistic sacrifice” (W. R. Smith, Old Testament in the Jewish Church, pp. 235 and 237). (Comp. Ezekiel 4:13.)

Hosea 9:3-4
3 They shall not dwell in the LORD'S land; but Ephraim shall return to Egypt, and they shall eat unclean things in Assyria.
4 They shall not offer wine offerings to the LORD, neither shall they be pleasing unto him: their sacrifices shall be unto them as the bread of mourners; all that eat thereof shall be polluted: for their bread for their soul shall not come into the house of the LORD.
