The L-rd spoke to Moses, saying: "Take the staff and assemble the congregation, you and your brother Aaron, and speak to the rock in their presence so that it will give forth its water. You shall bring forth water for them from the rock and give the congregation and their livestock to drink." Moses raised his hand and struck the rock with his staff twice, when an abundance of water gushed forth, and the congregation and their livestock drank. (Numbers 20:7-8, 11)

While the new generation is preparing to enter Israel, Miriam dies and there is a sudden lack of water. The people complain. G d tells Moses to take his staff, speak to the rock and command it to bring forth water. Facing the rock, staff in hand, Moses calls the people "rebels" and asks, "Can we draw water for you from this rock?"

At this crucial moment, instead of speaking to the stone, Moses raises his staff and strikes the rock twice. The force of the water rushes out from a deep hidden cistern, pouring over craggy jagged stones, almost sweeping away the watery figure of Moses. Flooded with frustration and sadness, Moses seems to losing his equilibrium while G‑d explains to him that because he failed to make G‑d holy in the eyes of the Israelites, he will not enter the Promised Land. The name of this place is "Mei Merivah", the waters of contention.
