Numbers 20:7-10

⁷And the Lord spake with Mosheh, saying,

⁸Take the rod, and gather the congregation together, thou and Aharon thy brother, and speak to the Rock, before their eyes, and it shall give its waters; and thou shalt bring forth water for them from the rock, and give drink to the congregation and their cattle.

⁹And Mosheh took the rod from before the Lord, as He had commanded him.

¹⁰And Mosheh and Aharon assembled the congregation before the rock; and he said to them: Hear now, rebels! Are we to draw forth water for you from this rock?
