'Do You Not Know' in the Bible

And he said to them, Do you not know this parable? How then will you know all parables?

Pilate said to him, Do you not speak to me? Do you not know that I have power to release you, and I have power to crucify you?

Do you not know that as many of us as were baptized in Christ were baptized in his death?

Your rejoicing is not good. Do you not know that a little leaven leavens the whole mass?

Do you not know that the saints shall judge the world? And if the world is judged by you, are you unworthy of the lowest courts?
