'Old' in the Bible

The heavens will perish, but Thou remainest; and they will all grow old like a garment,

By using the words, "a new Covenant," He has made the first one obsolete; but whatever is decaying and showing signs of old age is not far from disappearing altogether.

For by it the saints of old won God's approval.

Be careful not to refuse to listen to Him who is speaking to you. For if they of old did not escape unpunished when they refused to listen to him who spoke on earth, much less shall we escape who turn a deaf ear to Him who now speaks from Heaven.
