Isaiah 37:19
19. cast . . . gods into . . . fire—The policy of the Assyrians in order to alienate the conquered peoples from their own countries was, both to deport them elsewhere, and to destroy the tutelary idols of their nation, the strongest tie which bound them to their native land. The Roman policy was just the reverse.
Jeremiah 2:11
11. glory—Jehovah, the glory of Israel (Ps 106:20; Ro 1:23). The Shekinah, or cloud resting on the sanctuary, was the symbol of "the glory of the Lord" (1Ki 8:11; compare Ro 9:4). The golden calf was intended as an image of the true God (compare Ex 32:4, 5), yet it is called an "idol" (Ac 7:41). It (like Roman Catholic images) was a violation of the second commandment, as the heathen multiplying of gods is a violation of the first.
not profit— (Jer 2:8). Galatians 4:8
8-11. Appeal to them not to turn back from their privileges as free sons, to legal bondage again.
then—when ye were "servants" (Ga 4:7). ye knew not God—not opposed to Ro 1:21. The heathen originally knew God, as Ro 1:21 states, but did not choose to retain God in their knowledge, and so corrupted the original truth. They might still have known Him, in a measure, from His works, but as a matter of fact they knew Him not, so far as His eternity, His power as the Creator, and His holiness, are concerned. are no gods—that is, have no existence, such as their worshippers attribute to them, in the nature of things, but only in the corrupt imaginations of their worshippers (see on 1Co 8:4; 1Co 10:19, 20; 2Ch 13:9). Your "service" was a different bondage from that of the Jews, which was a true service. Yet theirs, like yours, was a burdensome yoke; how then is it ye wish to resume the yoke after that God has transferred both Jews and Gentiles to a free service?
