'Old' in the Bible

A day of darkness and thick darkness, A day of cloud and thick darkness, As darkness spread on the mountains, A people numerous and mighty, Like it there hath not been from of old, And after it there is not again -- till the years of generation and generation.

And it hath come to pass afterwards, I do pour out My Spirit on all flesh, And prophesied have your sons and your daughters, Your old men do dream dreams, Your young men do see visions.
