'Age' in the Bible

Even to your old age I will be the same,And even to your graying years I will bear you!I have done it, and I will carry you;And I will bear you and I will deliver you.

“No longer will there be in it an infant who lives but a few days,Or an old man who does not live out his days;For the youth will die at the age of one hundredAnd the one who does not reach the age of one hundredWill be thought accursed.
