Hosea 5:12

"And I am like the moth to Ephraim, and like the worm to the house of Judah." The moth and worm are figures employed to represent destructive powers; the moth destroying clothes (Isa 50:9; Isa 51:8; Psa 39:12), the worm injuring both wood and flesh. They are both connected again in Job 13:28, as things which destroy slowly but surely, to represent, as Calvin says, lenta Dei judicia. God becomes a destructive power to the sinner through the thorn of conscience, and the chastisements which are intended to effect his reformation, but which lead inevitably to his ruin when he hardens himself against them. The preaching of the law by the prophets sharpened the thorn in the conscience of Israel and Judah. The chastisement consisted in the infliction of the punishments threatened in the law, viz., in plagues and invasions of their foes.

The scope of this chapter is the same with that of the foregoing chapter, to discover the sin both of Israel and Judah, and to denounce the judgments of God against them. I. They are called to hearken to the charge (Hos 5:1, Hos 5:8). II. They are accused of many sins, which are here aggravated. 1. Persecution (Hos 5:1, Hos 5:2). 2. Spiritual whoredom (Hos 5:3, Hos 5:4). 3. Pride (Hos 5:5). 4. Apostasy from God (Hos 5:7). 5. The tyranny of the princes, and the tameness of the people in submitting to it (Hos 5:10, Hos 5:11). III. They are threatened with God's displeasure for their sins; he knows all their wickedness (Hos 5:3) and makes known his wrath against them for it (Hos 5:9). 1. They shall fall in their iniquity (Hos 5:5). 2. God will forsake them (Hos 5:6). 3. Their portions shall be devoured (Hos 5:7). 4. God will rebuke them, and pour out his wrath upon them (Hos 5:9, Hos 5:10). 5. They shall be oppressed (Hos 5:11). 6. God will be as a moth to them in secret judgments (Hos 5:12) and as a lion in public judgments (Hos 5:14). IV. They are blamed for the wrong course they took under their afflictions (Hos 5:13). V. It is intimated that they shall at length take a right course (Hos 5:15). The more generally these things are expressed of so much the more general use they are for our learning, and particularly for our admonition.

5:12 as a moth . . . rotten wood: Sin can destroy the very fabric and foundation of a people while leaving them unaware that the destruction has taken place.
