Charles Ellicott Commentary Hosea 7:8

"Ephraim, he mixeth himself among the peoples; Ephraim is a cake not turned." — Hosea 7:8 (ASV)

Cake not turned. Referring to the destructive effect of foreign influences. Ephraim was consumed by the unhallowed fire of Baal-worship, with all its passion and sensualism—a cake burnt on one side to a cinder, and on the other left in a condition utterly unfit for food. So the activity of foreign idolatries and foreign alliances, and the consequent unfaithfulness to Israel’s God, are the nation’s ruin.
