As we have heard, so have we seen in the city of the LORD of hosts, in the city of our God: God will establish it for ever. Selah. As we have heard, so have we seen - Our fathers have declared what mighty works thou didst in their time; and we have seen the same. God has often interposed and afforded us a most miraculous defense. So it was when they were invaded by the Assyrians, Syrians, Egyptians, Babylonians, Persians and the Greeks under Alexander.
The city of the Lord of hosts - His hosts defended the city, and it was known to be the City of the great King.
God will establish it for ever - This must refer to the true temple, the Christian Church, of which the Jewish Church was a type. The type perished, but the antitype remained, and will remain till time shall be no more.
Selah - So be it; and so it will be for evermore.
