In times of trouble, Israel had a habit of turning to foreign nations for help and protection. Instead of relying on God, the nation would form alliances with world powers like Assyria or Egypt. The point of a “half-baked cake” was to
say, in effect, that Israel’s actions were futile and self-destructive. God was saying that Israel was like a flat-cake left unturned on a hot fire-burned on one side, uncooked on the other. Such a cake would be good for nothing and rightly discarded.
HOSEA 7:8 – 8 Ephraim, he hath mixed himself among the people; Ephraim is a cake not turned.
