Numbers 20:7

5Why have you made us to come up out of Egypt, to bring us in to this evil place? It is no place of seed, or of figs, or of vines, or of pomegranates; neither is there any water to drink.”

6Moses and Aaron went from the presence of the assembly to the door of the Tent of Meeting, and fell on their faces. The LORD’s glory appeared to them.

7The LORD spoke to Moses, saying,

8“Take the rod, and assemble the congregation, you, and Aaron your brother, and speak to the rock before their eyes, that it pour out its water. You shall bring water to them out of the rock; so you shall give the congregation and their livestock drink.”

9Moses took the rod from before the LORD, as he commanded him.
