In Exodus 17, the people were thirsty. How did they respond?

They threatened to stone Moses to death

And 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?

And Moses cried unto the LORD, saying, What shall I do unto this people? they be almost ready to stone me. Exodus 17:3-4
