'Hereafter' in the Bible

Who among you will give ear to this?Who will give heed and listen hereafter?

Jesus *said to him, “You have said it yourself; nevertheless I tell you, hereafter you will see the Son of Man sitting at the right hand of Power, and coming on the clouds of heaven.”

Jesus answered and said to him, “What I do you do not realize now, but you will understand hereafter.”
