C. F. Keil and Franz Delitzsch on Hosea 4:17

Hos 4:17 “Ephraim is joined to idols, let it alone.” חבוּר עצבּים, bound up with idols, so that it cannot give them up. Ephraim, the most powerful of the ten tribes, is frequently used in the loftier style of the prophets for Israel of the ten tribes. הנּח־לו, as in 2Sa 16:11; 2Ki 23:18, let him do as he likes, or remain as he is. Every attempt to bring the nation away from its idolatry is vain. The expression hannach-lō does not necessitate the assumption, however, that these words of Jehovah are addressed to the prophets. They are taken from the language of ordinary life, and simply mean: it may continue in its idolatry, the punishment will not long be delayed.
