How did God water the army of Israel?

Answer 1

Exodus 17:6 describes how, at one point in the forty-year trek by the Israelites, Moses struck a rock and water gushed out for the thirsty Israelites. However, this miracle raises more questions than it answers. On the face of it, it would seem logistically impossible for at least two and a half million people to queue up at the stream, so presumable only the women did. But even six hundred thousand women would queue for days and would have to return to the queue as soon as they took their water ration back to their tents. And provision would have to be made for the Israelites' livestock to be watered. And it does not tell us how God watered the army for the rest of that long period in the wilderness. These questions are left unanswered.

Answer 2

Moses struck the rock with his staff and water gushed out (Exodus ch.17, Numbers ch.20).
