This is to be understood, either,
1. Of these graces or virtues in men. So the sense is, When that blessed time shall come, those virtues which now seem to be banished from human societies shall be restored, and there shall be a happy conjunction of mercy, or benignity; truth, or veracity; righteousness, or faithfulness; and peace, or peaceableness and concord. Or rather,
2. Of the blessings of God, of which the whole context speaks. And the sense is, That great work of redemption by Christ shall clearly manifest and demonstrate God's mercy in redeeming his people of Israel, and in the calling and conversion of the Gentiles; his truth, in fulfilling that great promise of the sending of his Son, which is the foundation of all the rest; his righteousness, in punishing sin or unrighteousness in his Son, and in conferring righteousness upon guilty and lost creatures; and his peace, or reconciliation to sinners, and that peace of conscience which attends upon it. Kissed each other; as friends use to do when they meet. See Exodus 4:27, Exodus 18:7. So this is another expression of the same thing.
