Verily thou art a God that {t} hidest thyself, O God of Israel, the Saviour.

(t) By this he exhorts the Jews to patience, though their deliverance is deferred for a time: showing that they would not repent their long patience, but the wicked and idolaters will be destroyed.

Wesley's Notes

45:15 Verily - These are the words of the prophet, on contemplation of the various dispensations of God towards his church, and in the world. Hidest - Thy counsels are deep and incomprehensible, thy ways are past finding out.

Jamieson-Fausset-Brown Bible Commentary

15. God that hidest thyself-Horsley, after Jerome, explains this as the confession of Egypt, &c., that God is concealed in human form in the person of Jesus. Rather, connected with Isa 45:9, 10, the prophet, contemplating the wonderful issue of the seemingly dark counsels of God, implies a censure on those who presume to question God's dealings (Isa 55:8, 9; De 29:29). Faith still discerns, even under the veil, the covenant-keeping "God of Israel, the Saviour" (Isa 8:17).

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.
