'Ages' in the Bible

in these last days did speak to us in a Son, whom He appointed heir of all things, through whom also He did make the ages;

But about the Son [the Father says to Him],“Your throne, O God, is forever and ever,And the scepter of [absolute] righteousness is the scepter of His kingdom.

Otherwise, He would have had to suffer many times since the foundation of the world. But now He has appeared one time, at the end of the ages, for the removal of sin by the sacrifice of Himself.

by faith we understand the ages to have been prepared by a saying of God, in regard to the things seen not having come out of things appearing;

Jesus Christ yesterday and to-day the same, and to the ages;

make you perfect in every good work to do His will, doing in you that which is well-pleasing before Him, through Jesus Christ, to whom is the glory -- to the ages of the ages! Amen.
