'Possible' in the Bible

Is it possible for two to go walking together, if not by agreement?

Is it possible for a bird to be taken in a net on the earth where no net has been put for him? will the net come up from the earth if it has taken nothing at all?

The cry of the lion is sounding; who will not have fear? The Lord God has said the word; is it possible for the prophet to keep quiet?

Is it possible for horses to go running on the rock? may the sea be ploughed with oxen? for the right to be turned by you into poison, and the fruit of righteousness into a bitter plant?
