Hath a nation changed their gods, which are yet no gods? but my people have changed their glory for that which doth not profit.
Glory - Yahweh, the glory of Israel (Psalms 106:20; Romans 1:23). The Shekinah, or cloud resting on the sanctuary, was the symbol of "the glory of the Lord" (1 Kings 8:11; cf. Romans 11:4). The golden calf was intended as an image of the true God (cf. Exodus 32:4-5, "These be thy gods (Hebrew, 'Elohiym (H430)), O Israel, which brought thee up out of Egypt. Tomorrow is a feast to the Lord;" yet it is called an "idol" - Acts 7:41, "They made a calf, and offered sacrifice unto the idol"). It (like Roman Catholic images) was a violation of the second commandment, as the pagan multiplying of gods is a violation of the first.
Not profit - (Jeremiah 2:8).
