Zechariah 12 Commentary

In Zechariah 12, the Suzerain God shifts from pronouncing a time of judgement and now promises to defend Judah and deliver her from all hostile nations. He will elevate her to prominence and defeat the nations who rise against her. Moreover, He will bestow a spirit of grace and supplication on all the Judeans, causing them to mourn bitterly for rejecting Him. At that time, all the clans of Judah will repent and turn to God in genuine faith. The passage's outline is as follows:

1. There will be a siege against Jerusalem in the future. The world will attack Judah, but the Lord God will guard Judah. He will cause blindness and confusion upon those who attack His people.
2. The LORD promises to defeat the adversaries of Judah and protect the weakest Israelites first. He will give every Israelite strength, so that they will be like fire burning in overwhelming force against their enemies. Even the poorest and weakest Israelite will fight with the strength of King David, and as an army they will fight with the power of God and His angel. The hostile forces who are gathered against Jerusalem will be destroyed that day.
3. All of the Jewish people, its rulers and priests and commoners, will mourn for God, whom they pierced. They will mourn so profoundly as though they had lost their firstborn son. Because of this mourning, God will pour His favor on all of Israel.

This prophecy likely looks to a siege in the End Times, where Jesus will save His people from their enemies (Revelation 16:16, 19:16, Zechariah 14:1-4). The section about Israel mourning that they pierced God is a clear allusion to the future event of Israel one day recognizing Jesus as their Messiah and repenting for rejecting Him. It seems that in doing so, then Jesus will return and deliver Israel, and rule as her King and God.
