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; Deu 29:29). Faith still discerns, even under the veil, the covenant-keeping "God of Israel, the Saviour" (Isa 8:17).
