Numbers 20:6-8

⁶And Mosheh and Aharon went up from before the congregation unto the door of the tabernacle of ordinance, and fell upon their faces; and the glory of the Lord was revealed to them.

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.
