Numbers 20:2-9 - The Waters Of Meribah
2 And there was not water for the assembly: and they will gather together against Moses and against Aaron. 3 And they will contend with Moses, and will speak, saying, Would that we died in the dying of our brethren before Jehovah! 4 And for what brought ye the gathering of Jehovah into this desert to die there, we and our cattle 5 And for what brought ye us up out of Egypt to bring us to this evil place? Not a place of seed, and figs, and the vine and the pomegranate; and not water to drink.
6 And Moses will go, and Aaron, from the face of the gathering to the door of the tent of appointment, and they will fall upon their faces: and the glory of Jehovah shall be seen to them. 7 And Jehovah will speak to Moses, saying, 8 Take the rod and gather the assembly together, thou and Aaron thy brother, and speak to the rock before their eyes; and it gave water; and brought to them water from the rock, and gave drink to the assembly, and their cattle.
9 And Moses will take the rod from before Jehovah, as he commanded him.
