4 Then Moses prayed to the Lord, “What am I going to do with these people? They are about to stone me to death!”
5 The Lord answered, “Take some of the leaders with you and go ahead of the rest of the people. Also take along the walking stick you used to strike the River Nile,
6 and when you get to the rock at Mount Sinai, I will be there with you. Strike the rock with the stick, and water will pour out for the people to drink.” Moses did this while the leaders watched.
7 The people had complained and tested the Lord by asking, “Is the Lord really with us?” So Moses named that place Massah, which means “testing” and Meribah, which means “complaining”.
8 When the Israelites were at Rephidim, they were attacked by the Amalekites.
9 So Moses told Joshua, “Have some men ready to attack the Amalekites tomorrow. I will stand on a hilltop, holding this walking stick that has the power of God.”
10 Joshua led the attack as Moses had commanded, while Moses, Aaron, and Hur stood on the hilltop.
