Moses asks this question out of frustration to rebuke the people for complaining. It can be translated as a statement. Alternate translation: "You complain that there is no water. Well, we will make water come out of this rock." or "You would not be happy even if we caused water to come out of this rock. But I will do it anyway." (See: [[rc://en/ta/man/jit/figs-rquestion]])
