Numbers 20:2-9 - The Waters Of Meribah
2 And there was no water for the assembly, and they gathered themselves together against Moses and against Aaron. 3 And the people contended with Moses, and spoke, saying, Would that we had died when our brethren died before Jehovah! 4 And why have ye brought the congregation of Jehovah into this wilderness, that we should die there, we and our beasts? 5 And why have ye made us to go up out of Egypt, to bring us 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.
6 And Moses and Aaron went from before the congregation to the entrance of the tent of meeting, and fell upon their faces; and the glory of Jehovah appeared to them. 7 And Jehovah spoke to Moses, saying, 8 Take the staff, and gather the assembly together, thou, and Aaron thy brother, and speak ye unto the rock before their eyes, and it shall give its water; and thou shalt bring forth to them water out of the rock, and shalt give the assembly and their beasts drink.
9 And Moses took the staff from before Jehovah, as he had commanded him.
