And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and pleas for mercy, so that, when they look on me, on him whom they have pierced, they shall mourn for him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.
My observation from chapter 11 of this study in Zechariah was that the prophecy made it clear that the Messiah would experience rejection in Jerusalem. And of course, that is exactly what Jesus foretold and experienced. But chapter 12 shows us that even though He is struck down, He is eventually accepted by the inhabitants of Jerusalem. It is God’s doing. God pours out His Spirit of grace and the nation cries out for mercy. And when they see “him whom they have pierced” (identified in the first person as God in this context), they will respond with heartfelt mourning and repentance.
The acceptance of Jesus is gradual in this day and age. It comes by exposure to the gospel, one life at a time. It comes by God’s gracious calling and the convicting work of the Spirit in those hearts that come to Him. God knows what He is doing. And Jews and Gentiles alike are finding a Messiah and a Savior in Jesus.
I believe this passage describes a future day when the nation of Israel will suffer its most difficult times. The response at the end of those times will be to turn to Messiah Jesus at His return. He is the one “whom they have pierced” (see John 19:31-37 where those who pierced Jesus’ side were Roman soldiers acting at the request of the Jewish authorities. Really we all are complicit). And the nation will come to Him as one nation, accepting the Messiah Who is the Savior of the world.
