Numbers 20:1-13

And the children of Israel, and all the multitude came into the desert of Sin in the first month: and the people abode in Cades. And Mary died there, and was buried in the same place. And the people, wanting water, came together against Moses and Aaron. And making a sedition, they said: Would God we had perished among our brethren before the Lord. Why have you brought out the church of the Lord into the wilderness, that both we and our cattle should die? Why have you made us come up out of Egypt, and have brought us into this wretched place which cannot be sowed: nor bringeth forth figs, nor vines, nor pomegranates: neither is there any water to drink? And Moses and Aaron leaving the multitude, went into the tabernacle of the covenant, and fell flat upon the ground, and cried to the Lord, and said: O Lord God, hear the cry of this people, and open to them thy treasure, a fountain of living water, that being satisfied they may cease to murmur. And the glory of the Lord appeared over them. And the Lord spoke to Moses, saying: Take the rod, and assemble the people together, thou and Aaron thy brother: and speak to the rock before them, and it shall yield waters. And when thou hast brought forth water out of the rock, all the multitude and their cattle shall drink. Moses therefore took the rod, which was before the Lord, as he had commanded him, And having gathered together the multitude before the rock, he said to them: Hear, ye rebellious and incredulous: Can we bring you forth water out of this rock? And when Moses had lifted up his hand, and struck the rock twice with the rod, there came forth water in great abundance, so that the people and their cattle drank, And the Lord said to Moses and Aaron: Because you have not believed me, to sanctify me before the children of Israel, you shall not bring these people into the land, which I will give them. This is the Water of contradiction, where the children of Israel strove with words against the Lord and he was sanctified in them.
