And I will make her that halted a remnant, and her that was cast far off a strong nation: and the LORD shall reign over them in mount Zion from henceforth, even for ever.
I will make her that halted a remnant - I will cause a remnant to remain which shall not perish.
And the Lord shall reign over them in mount Zion. David's kingdom shall be restored in the person of Messiah, who is the seed of David, and at the same time Yahweh (Isaiah 24:23).
From henceforth, even forever - (Isaiah 9:6-7; Daniel 7:14; Daniel 7:27; Luke 1:33; Revelation 11:15).
