'Mean' in the Bible

Say now to the rebellious house, Don't you know what these things mean? tell them, Behold, the king of Babylon came to Jerusalem, and took its king, and its princes, and brought them to him to Babylon:

What do you mean, that you use this proverb concerning the land of Israel, saying, The fathers have eaten sour grapes, and the children's teeth are set on edge?

Then I said to them, What does the high place where you go mean? So its name is called Bamah to this day.

When the children of your people shall speak to you, saying, Will you not show us what you mean by these?
