Numbers 20:6-9

6So Moses and Aaron went from the presence of the assembly to the door of the tabernacle of meeting, and they fell on their faces. And the glory of the Lord appeared to them.

7Then the Lord spoke to Moses, saying,

8“Take the rod; you and your brother Aaron gather the congregation together. Speak to the rock before their eyes, and it will yield its water; thus you shall bring water for them out of the rock, and give drink to the congregation and their animals.”

9So Moses took the rod from before the Lord as He commanded him.
