'Eternity' in the Bible

Blessed be Jehovah, the God of Israel, from eternity to eternity! Amen, and Amen.

Before the mountains were brought forth, and thou hadst formed the earth and the world, even from eternity to eternity thou art God.

Thy throne is established of old; thou art from eternity.

Blessed be Jehovah the God of Israel, from eternity and to eternity! And let all the people say, Amen! Hallelujah!
