Revelation 1:18-20

18and the One who lives. I was dead, but look—I am alive forever and ever! Moreover, I hold the keys of death and Sheol.

19Therefore write down what you have seen, what is, and what will happen after these things.

20As for the mystery of the seven stars that you saw in My right hand, and the seven golden menorot—the seven stars are the angels of Messiah’s seven communities, and the seven menorahs are the seven communities.”
