This chapter is designed for the comfort and encouragement of those that fear God and keep his commandments, even when they walk in darkness and have no light.

Observe, 1. How the people of God are here described, to whom the word of this consolation is sent and who are called upon to hearken to it, Isa. 51:1.

Both these proclamations, as I may call them, end alike with an assurance of the perpetuity of God’s righteousness and his salvation; and therefore we put them together, both being designed for the comfort of God’s people. Observe, I.

In these verses we have, I. A prayer that God would, in his providence, appear and act for the deliverance of his people and the mortification of his and their enemies. Awake, awake! put on strength, O arm of the Lord! Isa. 51:9. The arm of the Lord is Christ, or it is put for God himself, as Ps.

God, having awoke for the comfort of his people, here calls upon them to awake, as afterwards, Isa. 52:1. It is a call to awake not so much out of the sleep of sin (though that also is necessary in order to their being ready for deliverance) as out of the stupor of despair.
