'Rebels' in the Bible

And Moses and Aaron gathered the assembly together before the rock, and he said unto them, Hear now, ye rebels; shall we bring you forth water out of this rock?

and I will purge out from among you the rebels, and them that transgress against me; I will bring them forth out of the land where they sojourn, but they shall not enter into the land of Israel: and ye shall know that I am Jehovah.
