12:10 And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of {e} grace and of supplications: and they shall look upon me whom they have {f} pierced, and they shall mourn for {g} him, as one mourneth for [his] only [son], and shall be in bitterness for him, as one that is in bitterness for [his] firstborn.
(e) They will have the feeling of my grace by faith, and know that I have compassion on them.
(f) That is, whom they have continually vexed with their obstinacy, and grieved my Spirit. In Joh 19:37 it is referred to Christ's body, whereas here it is referred to the Spirit of God.
(g) They will turn to God by true repentance, whom before they had so grievously offended by their ingratitude.
12:10 I will pour - This was fulfilled on Christ's exaltation, when he sent the Comforter to his disciples, it is daily performed to the children of God, and will be continually, 'till we are brought to be with Christ for ever. The house of David - The whole family of Christ, his house who was the seed of David, and who is called David, Eze 37:24. The spirit of grace - Which is fountain of all graces in us. Pierced - Every one of us by our sins pierced him, and many of the Jews literally. Mourn - They shall literally lament the crucifying of the Lord Jesus. In bitterness - True repentance will bitterly lament the sins which brought sorrows and shame upon our Lord.
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.
