At Rephidim, the people quarrel with Moses over the lack of water, and God commands Moses to strike the rock at Horeb, from which water flows. The place is named Massah and Meribah, memorializing Israel's testing of God and contention with Moses. Amalek attacks Israel, and victory comes only while Moses holds up his hands, supported by Aaron and Hur, culminating in Joshua's defeat of Amalek and God's perpetual war against them.

The first person 'filled with the Spirit' was an artist
The very first person the Bible describes as 'filled with the Spirit of God' isn't a prophet or a king, it's Bezalel, a craftsman gifted for artistic design, gold-work and carving to build the Tabernacle (Exodus 31:1-5). Creativity itself is treated as a divine gift.
