That dwellest between the cherubims. — A like phrase in Psalms 18:10 refers, apparently, to the dark thunder-clouds of heaven. Here, probably, the reference is to the glory-cloud which was the symbol of the Divine presence, and which rested, when it manifested itself, between the cherubim of the ark (Numbers 7:89), those figures also symbolising the elemental forces of the heavens. (Comp. Psalms 68:33.)
Thou art the God, even thou alone. — The absolute monotheism of the faith of Israel is placed in strong antithesis to the polytheism of Rabshakeh (Isaiah 37:12). (Comp. Jeremiah 10:11, and Isaiah 40-42)
