Charles Ellicott Commentary Isaiah 45:19

"I have not spoken in secret, in a place of the land of darkness; I said not unto the seed of Jacob, Seek ye me in vain: I, Jehovah, speak righteousness, I declare things that are right." — Isaiah 45:19 (ASV)

I have not spoken in secret. —The words are in marked contrast to the thought expressed in Isaiah 45:15. God had been all along revealing Himself, not like the oracles of the heathen, in the gloom of caves and darkened shrines (Isaiah 8:19; Isaiah 65:4; Isaiah 29:4), but in the broad daylight of history and in the law written on men’s hearts. He had instructed men to seek Him not in chaos, but in a world of order, and to recognise His utterances by their righteousness.
