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.
In the visions of the prophet, those who have triumphed over sin and the grave are now seen happy in the presence of their Maker, talking freely with Him as man talked with God in the beginning. “Be ye glad,” the Lord bids them, “and rejoice forever in that which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy. And I will rejoice in Jerusalem, and joy in My people: and the voice of weeping shall be no more heard in her, nor the voice of crying.” “The inhabitant shall not say, I am sick: the people that dwell therein shall be forgiven their iniquity.” PK 729.1
“In the wilderness shall waters break out,
And streams in the desert.
And the parched ground shall become a pool,
And the thirsty land springs of water.” PK 729.2
“Instead of the thorn shall come up the fir tree,
And instead of the brier shall come up the myrtle tree.” PK 729.3
