'From Everlasting to Everlasting' in the Bible

Before the mountains were brought forth, or ever You had formed the earth and the world, even from everlasting to everlasting You are God.

But the mercy of Jehovah is from everlasting to everlasting on those who fear Him, and His righteousness is to sons of sons;

Blessed is Jehovah, the God of Israel from everlasting to everlasting; and let all the people say, Amen. Praise Jehovah!
