Water from God.
Exodus 15:22-27, 17:1-7
Exodus 15:22 Then Moses took Israel from the Red Sea, and they went forth into the desert of Shur. And they wandered for three days through the wilderness, and they found no water.
Exodus 15:23 And they arrived at Marah. They were unable to drink the waters of Marah because they were bitter. Therefore, he also established a name befitting the place, calling it ‘Marah,’ that is, bitterness.
Exodus 15:24 And the people murmured against Moses, saying: “What shall we drink?”
Exodus 15:25 So he cried out to the Lord, who showed him a tree. And when he had cast it into the waters, they were turned into sweetness. In that place, he established instructions for him, and also judgments. And he tested him there,
Exodus 15:26 saying: “If you will listen to the voice of the Lord your God, and do what is right in his sight, and obey his commands, and keep all his precepts, I will not bring upon you any of the distress that I imposed on Egypt. For I am the Lord, your healer.”
Exodus 15:27 Then the sons of Israel arrived in Elim, where there were twelve fountains of water and seventy palm trees. And they camped next to the waters.
Exodus 17:1 And so, the entire multitude of the sons of Israel, having set out from the desert of Sin in stages, according to the word of the Lord, made camp at Rephidim, where there was no water for the people to drink.
Exodus 17:2 And arguing against Moses, they said, “Give us water, so that we may drink.” And Moses answered them: “Why argue against me? For what reason do you tempt the Lord?”
Exodus 17:3 And so the people were thirsty in that place, due to the scarcity of water, and they murmured against Moses, saying: “Why did you cause us to go out of Egypt, so as to kill us and our children, as well as our cattle, with thirst?”
Exodus 17:4 Then Moses cried out to the Lord, saying: “What shall I do with this people? A little while more and they will stone me.”
Exodus 17:5 And the Lord said to Moses: “Go before the people, and take with you some of the elders of Israel. And take in your hand the staff, with which you struck the river, and advance.
Exodus 17:6 Lo, I will stand in that place before you, on the rock of Horeb. And you shall strike the rock, and water will go forth from it, so that the people may drink.” Moses did so in the sight of the elders of Israel.
Exodus 17:7 And he called the name of that place ‘Temptation,’ because of the arguing of the sons of Israel, and because they tempted the Lord, saying: “Is the Lord with us, or not?”
