Do in the dark, i.e., in secret. Hence the difficulty of access to the place of their worship. The ordinary idolatries of Israel, as of most heathen, consisted in the worship of the true, or of a supposed spiritual Deity, by means of sensible images (comp. Exodus 32:8). This was open and public enough at Jerusalem at this time; but the peculiar sin here portrayed was the actual worship of the creature by means of images and paintings. This, although joined in by the chief people of the nation, was practised secretly, perhaps, not only for the purpose of concealing its Egyptian tendencies from the Chaldæans, but also to throw over it the charm of mystery, as was so common among the heathen.
Every man in the chambers of his imagery. — By “chambers of imagery” (the same word as in Leviticus 26:1) is intended chambers painted with images like the one now shown to the prophet. This was not a solitary case; on the contrary, it was but an example of what was done everywhere. The people stifled the voice of conscience then, as in every age, by saying “The LORD seeth us not,” comp. Psalms 10:11; Psalms 94:7, &c. Yet, besides this, they argued, doubtless from the calamities that had already fallen upon their country, “the LORD hath forsaken the earth,” or. rather, the land; and therefore they must have recourse to other help. But the prophet was to see yet worse things.
