And We sundered them into twelve tribes as communities. And We revealed to Moses when his folk asked him for water: Strike the rock with thy staff. Then, burst forth out of it twelve springs: Surely, each clan knew its drinking place. And We shaded them with cloud shadows. We caused to descend manna and the quails for them. Eat of what is good that We provided you! And they did not wrong Us, but they had been doing wrong to themselves.
