What is the meaning of Revelation 20:6?

* The two F.O.G. Bibles & Commentary below are currently a work in progress.

Blessed and holy are those who share in the first resurrection! The second death has no power over them, but they will be priests of God and of Christ, and will reign with Him for a thousand years.

Berean Standard Bible (BSB)

Strong's King James

(6) Blessed and set apart (holy), the one having a share in the first resurrection! Upon these, the second death has no authority, rather they will be priests of אֱלֹהִים Elohim and Mashiach and will reign as kings with Him, a 1,000 years.

The F.O.G*

[6] Blessed and holy are those who share in the first resurrection! The second death has no power over them. They will serve as priests of יהוה and of the Messiah, reigning with Him for a thousand years.

The F.O.G Paraphrase

Happy and holy is he who is having part in the first rising again; over these the second death hath not authority, but they shall be priests of God and of the Christ, and shall reign with him a thousand years.
