Hosea 7-9

Ephraim is like a dove,
   easily deceived and senseless—
now calling to Egypt,
   now turning to Assyria. (Hosea 7:11)

Apparently the leaders of the Tribe of Ephraim sought to maintain their power and position by making alliances first with one foreign power, then another, as it seemed beneficial to them in the moment. This strategy is called "political opportunism" or "political necessity," but Hosea named it naive, senseless, or as "flighty as a bird."
