Matthew Poole and continuators on Zechariah 12:9

9 ¶ And it shall come to pass in that day, that I will seek to destroy all nations that come against Jerusalem .

This also shall certainly come to pass.

God the Defender and Saviour of Israel.

This speaks not any difficulty to God in the work, as with men, who sometimes do seek to do what they cannot do, but this implyeth God would throughly do it, his right hand should find out these his Enemies, he will hunt them out.

Not to restrain, but to overthrow and destroy.

Without partiality, every nation that sets it self to oppress and destroy Jerusalem, God will pay them in their own Coin, they said blot out her Name, but God will blot out theirs; let us, say they, cut them off from being a Nation, but this God will turn upon their own heads.

Combine, and attempt to destroy her, and this was evidently seen upon those that sought to destroy Jerusalem, and the second Temple before Christ's Incarnation: for by the Romans God destroyed the Antiochian Power which had often mischiefed the Jews, and destroy'd the other Kingdoms which had been Enemies to the Jews, who were never in danger of being cut off from being a Nation, till their horrid murthering of the Lord of Life.

Literally and historically the City which the Captives returned from Babylon did build, but mystically the Catholick Church which God will never suffer to be destroyed, he will rather destroy all Nations, than suffer them to destroy his Church.
