The chapter begins with a call to Zion: awake, put on your strength, put on your beautiful garments, Jerusalem, the holy city, for the uncircumcised and the unclean will never again enter you. Shake yourself from the dust, rise up, loose the bonds from your neck. The Lord recalls that they were sold for nothing and will be redeemed without money. His people went down to Egypt as sojourners, and Assyria oppressed them without cause. Now his people are taken away for nothing, their rulers wail and his name is continually blasphemed. Therefore his people will know his name and know that he is the one who speaks.
Verses 7 through 10 are a celebration. How beautiful on the mountains are the feet of the messenger who announces peace, who brings good news of good things, who announces salvation and says to Zion: your God reigns! The watchmen lift up their voices and sing together, for they see with their own eyes the Lord's return to Zion. The ruins of Jerusalem break into joy, for the Lord has comforted his people and redeemed Jerusalem. The Lord has bared his holy arm before the eyes of all the nations, and all the ends of the earth will see the salvation of our God.
Verses 11 and 12 command them to leave: depart, go out from there, touch no unclean thing, purify yourselves, you who carry the vessels of the Lord. They will not go out in haste or flee, for the Lord will go before them, and the God of Israel will be their rear guard. Verses 13 through 15 open a new theme: my servant will prosper, he will be raised and lifted up and highly exalted. Just as many were astonished at him, because his appearance was marred beyond that of any man, so he will sprinkle many nations; kings will shut their mouths because of him, for they will see what had not been told them and understand what they had not heard.
