Matthew Henry on Isaiah 40:27–end
Here, I. The prophet reproves the people of God, who are now supposed to be captives in Babylon for their unbelief and distrust of God, and the dejections and despondencies of their spirit under their affliction (Isa 40:27): "Why sayest thou, O Jacob! to thyself and to those about thee, My way is hidden from the Lord?
