Verse 9. - I will seek to destroy. It shall be always my aim and my care to destroy the enemies of the Church, that they shall never prevail against it. The words cannot apply to the literal Jerusalem, against which no such confederacy of nations was ever formed.

12:9-14 The day here spoken of, is the day of Jerusalem's defence and deliverance, that glorious day when God will appear for the salvation of his people. In Christ's first coming he bruised the serpent's head, and broke all the powers of darkness that fought against God's kingdom among men. In his second coming he will complete their destruction, when he shall put down all opposing rule, principality, and power; and death itself shall be swallowed up in that victory. The Holy Spirit is gracious and merciful, and is the Author of all grace or holiness. He, also, is the Spirit of supplications, and shows men their ignorance, want, guilt, misery, and danger. At the time here foretold, the Jews will know who the crucified Jesus was; then they shall look by faith to him, and mourn with the deepest sorrow, not only in public, but in private, even each one separately. There is a holy mourning, the effect of the pouring out of the Spirit; a mourning for sin, which quickens faith in Christ, and qualifies for joy in God. This mourning is a fruit of the Spirit of grace, a proof of a work of grace in the soul, and of the Spirit of supplications. It is fulfilled in all who sorrow for sin after a godly sort; they look to Christ crucified, and mourn for him. Looking by faith upon the cross of Christ will cause us to mourn for sin after a godly sort.And it shall come to pass in that day,.... So often mentioned in this chapter; by which is meant the latter part of the Gospel dispensation, the spiritual reign of Christ:

that I will seek to destroy all the nations that come against Jerusalem; and shall destroy them. The whole of this paragraph seems to refer to the same as in Ezekiel 38:1.
