I have not spoken in secret, {x} in a dark place of the earth: I have not said to the seed of Jacob, Seek ye me in vain: I the LORD speak righteousness, I declare things that are right.

(x) As do the false gods, who give uncertain answers.

Wesley's Notes

45:19 In secret - The Heathen idols deliver oracles in obscure cells and caverns: but I have delivered my oracles to Israel publickly and plainly. In vain - Serve and worship me for nought. As I appointed them work, so from time to time I have given them abundant recompence. Right - I require nothing of my people which is not highly just and good.

Jamieson-Fausset-Brown Bible Commentary

19. not . secret-not like the heathen oracles which gave their responses from dark caverns, with studied obscurity (Isa 48:16). Christ plainly quotes these words, thereby identifying Himself with Jehovah (Joh 18:20).

I said not . Seek . in vain-When I commanded you to seek Me (Jehovah did so, Isa 45:11, "Ask Me," &c.), it was not in order that ye might be sent empty away (De 32:47). Especially in Israel's time of trial, God's interposition, in behalf of Zion hereafter, is expressly stated as about to be the answer to prayer (Isa 62:6, 7-10; Ps 102:13-17, 19-21). So in the case of all believers, the spiritual Israel.

righteousness-that which is veracious: not in the equivocal terms of heathen responses, fitly symbolized by the "dark places" from which they were uttered.

right-true (see on [813]Isa 41:26).

Matthew Henry's Concise Commentary

45:11-19 Believers may ask in prayer for what they need; if for their good, it will not be withheld. But how common to hear God called to account for his dealings with man! Cyrus provided for the returning Jews. Those redeemed by Christ shall be provided for. The restoration would convince many, and convert some; and all that truly join the Lord, find his service perfect freedom. Though God be his people's God and Saviour, yet sometimes he lays them under his frowns; but let them wait upon the Lord who hides his face. There is a world without end; and it will be well or ill with us, according as it shall be with us in that world. The Lord we serve and trust, is God alone. All that God has said is plain, satisfactory, and just. As God in his word calls us to seek him, so he never denied believing prayers, nor disappointed believing expectations. He gives grace sufficient, and comfort and satisfaction of soul.
