Now a man who is clean shall gather up the ashes of the heifer and deposit them outside the camp in a clean place, and the congregation of the sons of Israel shall keep it as water to remove impurity; it is purification from sin.

So the people came to Moses and said, “We have sinned, because we have spoken against the Lord and you; intercede with the Lord, that He may remove the serpents from us.” And Moses interceded for the people.
