Êxodo 17 - Bíblia Online

And all the congregation of the children of Israel set out on their journey from the Wilderness of Sin, at the mouth of Jehovah, and camped in Rephidim; and there was no water for the people to drink. 
Therefore the people quarreled with Moses, and said, Give us water, that we may drink. And Moses said to them, Why do you quarrel with me? Why do you tempt Jehovah? 
And the people thirsted there for water, and the people grumbled against Moses, and said, Why is it you have brought us up out of Egypt, to kill us and our children and our livestock with thirst? 
And Moses cried out to Jehovah, saying, What shall I do with this people? They are almost ready to stone me! 
And Jehovah said to Moses, Pass over before the people, and take with you some of the elders of Israel. Also take in your hand your staff with which you struck the river, and go. 
Behold, I will stand before you there on the rock in Horeb; and you shall strike the rock, and water will come out of it, that the people may drink. And Moses did so before the eyes of the elders of Israel. 
And he called the name of the place Massah and Meribah, because of the quarreling of the children of Israel, and because they tempted Jehovah, saying, Is Jehovah in our midst or not? 
And Amalek came and fought against Israel in Rephidim. 
And Moses said to Joshua, Choose some men and go fight against Amalek. Tomorrow I will stand on the top of the hill with the staff of God in my hand. 
So Joshua did as Moses said to him, to fight against Amalek. And Moses, Aaron, and Hur went up to the top of the hill. 
And so it was, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. 
But Moses hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun. 
And Joshua defeated Amalek and his people with the edge of the sword. 
And Jehovah said to Moses, Write this for a memorial in the book and recount it in the ears of Joshua, that I will utterly blot out the remembrance of Amalek from under the heavens. 
And Moses built an altar and called its name, Jehovah-My-Banner; 
saying, Because Jehovah has sworn with His hand on the throne: Jehovah is at war with Amalek from generation to generation.
