(10) Rejoice ye with Jerusalem . . .--The holy city is still thought of as a mother rejoicing in her new-born child; friends and neighbours (i e., the nations friendly to Israel) who had shown pity for her sufferings are now invited to participate in her joy.

Verse 10. - Rejoice ye with Jerusalem... all ye that love her. The call to rejoicing is general. Restored Jerusalem is to be hailed with joy "by all who love her," whether her own children or foreigners. To both she will be a blessing (vers. 11-13).

66:5-14 The prophet turns to those that trembled at God's word, to comfort and encourage them. The Lord will appear, to the joy of the humble believer, and to the confusion of hypocrites and persecutors. When the Spirit was poured out, and the gospel went forth from Zion, multitudes were converted in a little time. The word of God, especially his promises, and ordinances, are the consolations of the church. The true happiness of all Christians is increased by every convert brought to Christ. The gospel brings with it, wherever it is received in its power, such a river of peace, as will carry us to the ocean of boundless and endless bliss. Divine comforts reach the inward man; the joy of the Lord will be the strength of the believer. Both God's mercy and justice shall be manifested, and for ever magnified.Rejoice ye with Jerusalem, and be glad with her,.... The church; she bringing forth so many spiritual children to Christ; just as, when a woman is delivered of a child, her friends and neighbours congratulate her upon it, and rejoice with her on that account; as Elisabeth's neighbours and relations did, at the birth of John the Baptist, Luke 1:57, so the church's friends here are called together to rejoice with her, at the numerous birth and conversion of souls in her, than which nothing is more joyful to the saints; see Luke 15:6,

all ye that love her; wish her well, and pray for her peace and prosperity; all that love God love his church, the habitation of his house, the place where his honour dwells; all that love Christ love her who is his spouse and bride, and purchased by his blood; all that love the word and ordinances love the church where they are administered:

rejoice for joy with her, all ye that mourn for her; that had mourned for her, when things went ill with her; these are they that mourn in Zion, and for Zion, because of the sins of her professors; corruptions in doctrine, discipline, and worship; declensions in grace; want of love to one another, and few instances of conversion: but now things being the reverse, and it going well with her, they are called upon to rejoice exceedingly with her; for such is the sympathizing spirit of the saints, that they rejoice with them that rejoice, and weep with them that weep, Romans 12:15.
