Exodus 17:2-7

2Wherefore the people did chide with Moses, and said, Give us water that we may drink. And Moses said unto them, Why chide ye with me? wherefore do ye tempt Yhwh?

3And the people thirsted there for water; and the people murmured against Moses, and said, Wherefore is this that thou hast brought us up out of Egypt, to kill us and our children and our cattle with thirst?

4And Moses cried unto Yhwh, saying, What shall I do unto this people? they be almost ready to stone me.

5And Yhwh said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go.

6Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.

7And he called the name of the place Massah, and Meribah, because of the chiding of the children of Israel, and because they tempted Yhwh, saying, Is Yhwh among us, or not?12
