Isaiah 45:15

(15) Verily thou art a God that hidest thyself . . .—The words have been variously taken: (1) as continuing the wondering homage of the heathen; (2) as spoken by the prophet as he surveys the unsearchable ways of God. (Comp. Romans 11:33.) Through the long years of exile He had seemed to hide Himself, to be negligent of His people (Isaiah 8:17; Isaiah 54:8; Psalms 55:1) or unable to help them. Now it would be seen that He had all along been as the Strong one (El) working for their deliverance.
