Isaiah 32:15

Until the Spirit be poured upon us, &c. And this calamity shall, in a manner, continue until the time come in which God will pour, or, as יערה, properly signifies, reveal, that is, evidently and plentifully confer his Spirit upon his people. Which was done, in some sort, upon their return from Babylon, when God, by his Spirit, moved Cyrus to give them liberty of returning to Jerusalem, and the people to return and build the city and temple. But it was far more clearly and fully accomplished in the days of the Messiah, when God's Spirit was in a most evident and glorious manner poured forth upon the apostles and other believing Jews, to the astonishment of their very adversaries; and when the following promises were, in a good measure, fulfilled, and are more fully to be accomplished in God's due time.

See on Isaiah 29:17.
