Exodus 17:1-3

The whole Israelite community left the Desert of Sin and traveled from place to place, as the LORD commanded. They camped at Rephidim, but there was no water there for the people to drink. So they quarreled with Moses and said, “Give us water to drink.” Moses said to them, “Why do you quarrel with me? Why are you testing the LORD?” But the people were very thirsty for water, so they grumbled against Moses. They said, “Why did you bring us out of Egypt? Was it to kill us, our children, and our farm animals with thirst?”
