'Hereafter' in the Bible

Write the things which thou hast seen, and the things which are, and the things which shall be hereafter;

After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.

One woe is past; and, behold, there come two woes more hereafter.
