621 Because of Zion I will not keep quiet, and because of Jerusalem I will take no rest, till her righteousness goes out like the shining of the sun, and her salvation like a burning light. 2 And the nations will see your righteousness, and all kings your glory: and you will have a new name, given by the mouth of the Lord. 3 And you will be a fair crown in the hand of the Lord, and a king's head-dress in the hand of your God. 4 You will not now be named, She who is given up; and your land will no longer be named, The waste land: but you will have the name, My pleasure is in her, and your land will be named, Married: for the Lord has pleasure in you, and your land will be married.
Matthew Henry's Commentary on Isaiah 62:1-4
Commentary on Isaiah 62:1-5
(Read Isaiah 62:1-5)
The Son of God here assures his church of his unfailing love, and his pleading for her under all trails and difficulties. She shall be called by a new name, a pleasant name, such as she was never called by before. The state of true religion in the world, before the preaching of the gospel, no man seemed to have any real concern for. God, by his grace, has wrought that in his church, which makes her his delight. Let us thence learn motives to holiness. If the Lord rejoices over us, we should rejoice in his service.
