The people of Israel were thirsty... God’s tells Moses exactly what to do to solve the problem. He says, “I will stand before you by the rock… all you got to do is hit the rock with your staff…" So Moses takes the same staff that split the seas wide open for them to walk through and He obeys God's new strange request and the Rock split open so there was water to drink!

The things God asks, don’t always make sense. 

But they don’t need to make sense to make God right!
