Revelation 1:7-8

7Look! He comes with the clouds of heaven. And everyone will see him— even those who pierced him. And all the nations of the world will mourn for him. Yes! Amen!

8“I am the Alpha and the Omega—the beginning and the end,” says the Lord God. “I am the one who is, who always was, and who is still to come—the Almighty One.”
