'Ages' in the Bible

Now these things happened unto them by way of example; and they were written for our admonition, upon whom the ends of the ages are come.

that in the ages to come he might show the exceeding riches of his grace in kindness toward us in Christ Jesus:

and to make all men see what is the dispensation of the mystery which for ages hath been hid in God who created all things;

even the mystery which hath been hid for ages and generations: but now hath it been manifested to his saints,

else must he often have suffered since the foundation of the world: but now once at the end of the ages hath he been manifested to put away sin by the sacrifice of himself.

And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, O Lord God, the Almighty; righteous and true are thy ways, thou King of the ages.
