Zechariah 12:10

And I will pour upon the house of David, the entire royal family, the royal priesthood of the Church of the New Testament, and upon the inhabitants of Jerusalem, the members of His congregation in general, the Spirit of grace and of supplications, Him who works in the heart of man the certainty of the divine grace and urges him to seek forgiveness of sins by daily prayer; and they shall look upon Me whom they have pierced, as they nailed their Redeemer to the cross, John 19:34; Revelation 1:7, and they shall mourn for Him as one mourneth for his only son, acknowledging their transgression in killing the Prince of Life, Acts 3:15, and shall be in bitterness for Him as one that is in bitterness for his firstborn, almost the greatest grief and sorrow known to the Jews.
