'Ages' in the Bible

Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;

and to shed light for all about the administration of the mystery hidden for ages in God who created all things.

with regard to the fulfillment of the times [that is, the end of history, the climax of the ages]—to bring all things together in Christ, [both] things in the heavens and things on the earth.

This is according to His eternal purpose accomplished in the Messiah, Jesus our Lord.

Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.

That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
