Compare Acts 2:17. Peter distinctly appropriates these prophecies (marginal references) to the outpouring of the Holy Spirit on the day of Pentecost, and the inauguration of the Church of Christ by that miraculous event. This was the beginning of the fulfillment. They shall find their consummation when time shall be no more.

For I have poured out my Spirit - That is, I will pour out my Spirit; see the notes on Ezekiel 36:25-29 (note), where this subject is largely considered. This Spirit is to enlighten, quicken, purify, and cleanse their hearts; so that, being completely changed, they shall become God's people, and be a praise in the earth. Now, they are a proverb of reproach; then, they shall be eminently distinguished.

Neither will I hide my face any more from them,.... The Jews, upon their future conversion, will always have the worship of God among them, and his presence with them; he will always take notice of them; they will ever be under his protection and care; he will never remove his Shechinah from them any more, as the Targum: a further proof that this refers to future times; for, after their return from Babylon, God did hide his face, and remove his presence from them, and left them to ruin and destruction by the Romans:

for I have poured out my Spirit upon the house of Israel, saith the Lord God; this refers not to the effusion of the Spirit on the day of Pentecost, but to one that is yet to come, when the Jews will be converted in the latter day; after which God will no more depart from them, nor shall they depart from him; see Zechariah 12:10.

Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord GOD.

29. poured out my Spirit upon . Israel-the sure forerunner of their conversion (Joe 2:28; Zec 12:10). The pouring out of His Spirit is a pledge that He will hide His face no more (2Co 1:22; Eph 1:14; Php 1:6).

39:23-29 When the Lord shall have mercy on the whole house of Israel, by converting them to Christianity, and when they shall have borne the shame of being cast off for their sins, then the nations shall learn to know, worship, and serve him. Then Israel also shall know the Lord, as revealed in and by Christ. Past events do not answer to these predictions. The pouring out of the Spirit is a pledge that God's favour will continue. He will hide his face no more from those on whom he has poured out his Spirit. When we pray that God would never cast us from his presence, we must as earnestly pray that, in order thereto, he would never take his Holy Spirit from us.
