Water at Rephidim
At Rephidim, Israel again complained, fearing for survival without water. Moses, pressured by the people, cried out to God. The Lord instructed him to strike the rock at Horeb, and water flowed forth. The place was named Massah (testing) and Meribah (quarreling), terms later remembered in Psalm 95 and Hebrews 3 as examples of unbelief. The issue was not thirst itself—an understandable human need—but the way Israel voiced it in distrust. God was training them to ask in faith rather than accuse in doubt. The event at Rephidim became a central lesson in how God provides for His people.
Battle with Amalek
Immediately after this episode, Amalek attacked Israel. Joshua led the fighters while Moses, standing with the staff of God on the hill, lifted his hands with the staff. As long as his hands were raised, Israel prevailed. When fatigue set in, Aaron and Hur supported him until sunset, ensuring victory. Afterward, Moses built an altar and called it Jehovah-nissi—“The LORD is my banner”—confessing that victory came not by military strength but by God’s hand. This battle with Amalek became a lasting reminder that God fights for His people, and that true leadership points back to God’s strength.
Lessons of Leadership
The episode with Amalek raises a striking question: why did Moses need to act at all by lifting up the staff? Couldn’t God have granted victory without this display? The raised hands were not effortless; Moses struggled, and his fatigue made clear that this was no mere ritual. His weakness forced the people to see that the outcome did not rest on a man’s endurance but on God’s power. When his arms dropped, Israel faltered; when supported, they prevailed. T
his back-and-forth underscored that victory belonged to the LORD, not to human effort, and that the visible sign was meant to teach dependence. In this way, the struggle itself became part of the lesson: the LORD was their banner, and only under Him could they stand.
This chapter highlights how God trained both His people and their leader. The Israelites had to learn how to petition rightly: not by murmuring, but by bringing needs before God through prayer. Moses also had to grow. At times he waited until complaints reached a breaking point before turning to God, but later, as in the golden calf incident (Exod. 32–34), he would intercede immediately and boldly. Like a parent guiding children, God provided for Israel’s needs while also shaping their hearts. Their discomfort revealed whether they would respond with fear or with trust.
Moses himself was being refined as a leader. At his calling he raised concerns about his mission, but he never asked how food and water would be provided. Had he asked, God surely could have given him a roadmap. Instead, God unfolded His provision step by step, teaching Moses faith and dependence. Soon after, in Exodus 18, Moses learned to share leadership by appointing judges to handle daily matters so that he could focus on the most serious cases before God.
