Isaiah 52:1

Here, I. God's people are stirred up to appear vigorous for their own deliverance, Isa 52:1, Isa 52:2. They had desired that God would awake and put on his strength, Isa 51:9. Here he calls upon them to awake and put on their strength, to bestir themselves; let them awake from their despondency, and pluck up their spirits, encourage themselves and one another with the hope that all will be well yet, and no longer succumb and sink under their burden. Let them awake from their distrust, look above them, look about them, look into the promises, look into the providences of God that were working for them, and let them raise their expectations of great things from God. Let them awake from their dullness, sluggishness, and incogitancy, and raise up their endeavours, not to take any irregular courses for their own relief, contrary to the law of nations concerning captives, but to use all likely means to recommend themselves to the favour of the conqueror and make an interest with him. God here gives them an assurance, 1.
