'End of the Age' in the Bible

While He was sitting on the Mount of Olives, the disciples came up to Him by themselves, and said, "Tell us when this is to take place, and what will be the sign of your coming and of the end of the age."

And I will ask I will ask the Father and He will give you another Helper, to remain with you to the end of the age;

who was foreordained for it before the foundation of the world but was brought out to public view at the end of the ages, for the sake of you
