Two passages of story are recorded in this chapter, I. The watering of the host of Israel. 1. In the wilderness they wanted water (Exo 17:1). 2. In their want they chided Moses (Exo 17:2, Exo 17:3). 3. Moses cried to God (Exo 17:4). 4. God ordered him to smite the rock, and fetch water out of that; Moses did so (Exo 17:5, Exo 17:6). 5. The place named from it (Exo 17:7). II. The defeating of the host of Amalek. 1. The victory obtained by the prayer of Moses (Exo 17:8-12). 2. By the sword of Joshua (Exo 17:13). 3. A record kept of it (Exo 17:14, Exo 17:16). And these things which happened to them are written for our instruction in our spiritual journey and warfare.
