Rejoice ye with Jerusalem - The idea which is presented in this verse is, that it is the duty of all who love Zion to sympathize in her joys. It is one evidence of piety to rejoice in her joy; and they who have no true joy when God pours down his Spirit, and, in a revival of religion, produces changes as sudden and transforming as if the earth were suddenly to pass from the desolation of winter to the verdure and bloom of summer; or when the gospel makes rapid advances in the pagan world, have no true evidence that they love God or his cause. Such scenes awaken deep interest in the bosoms of angels, and in the bosom of God the Saviour; and they who love that God and Saviour will rejoice in such scenes, and will mingle their joys and thanksgivings with the joys and thanksgivings of those who are thus converted and saved.

All ye that mourn for her - That sympathize in her sorrows, and that mourn over her desolations.

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.

In the anticipation of such a future, those who inwardly participate in the present sufferings of Zion are to rejoice beforehand in the change of all their suffering into glory. "Rejoice ye with Jerusalem, and exult over her, all ye that love her; be ye delightfully glad with her, all ye that mourn over her, that he may suck and be satisfied with the breast of her consolations, that ye may sip and delight yourselves in the abundance of her glory." Those who love Jerusalem (the abode of the church, and the church itself), who mourn over her (hith'abbēl, inwardly mourn, 1 Samuel 15:35, prove and show themselves to be mourners and go into mourning, b. Mod katan 20b, the word generally used in prose, whereas אבל, to be thrown into mourning, to mourn, only occurs in the higher style; compare ציּון אבלי, Isaiah 57:18; Isaiah 61:2-3; Isaiah 60:20), these are even now to rejoice in spirit with Jerusalem and exult on her account (bâh), and share her ecstatic delight with her ('ittâh), in order that when that in which they now rejoice in spirit shall be fulfilled, they may suck and be satisfied, etc. Jerusalem is regarded as a mother, and the rich actual consolation, which she receives (Isaiah 51:3), as the milk that enters her breasts (shōd as in Isaiah 60:16), and from which she now supplies her children with plentiful nourishment. זיז, which is parallel to שׁד (not זיו, a reading which none of the ancients adopted), signifies a moving, shaking abundance, which oscillates to and fro like a great mass of water, from זאזא, to move by fits and starts, for pellere movere is the radical meaning common in such combinations of letters as זא, זע, רא, Psalm 42:5, to which Bernstein and Knobel have correctly traced the word; whereas the meaning emicans fluxus (Schrder), or radians copia (Kocher), to pour out in the form of rays, has nothing to sustain it in the usage of the language.

Rejoice ye with Jerusalem, and be glad with her, all ye that love her: rejoice for joy with her, all ye that mourn for her:

10. love . mourn for her-(Ps 102:14, 17, 20; 122:6).

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.
