Revelation 1:7-8
7 Behold, He is coming with clouds, and every eye will see Him, even they who pierced Him. And all the tribes of the earth will mourn because of Him. Even so, Amen.
8 “I am the Alpha and the Omega, [a]the Beginning and the End,” says the Lord, “who is and who was and who is to come, the Almighty.”
