While Moses lifted up his hand, Joshua fought for the people and prevailed. Moses lifting up his hand on the mountaintop typifies the ascended Christ interceding in the heavens (Rom. 8:34b; Heb. 7:25; cf. 1 Tim. 2:8), and Joshua typifies Christ as the indwelling Spirit fighting against the flesh (Rom. 8:9-11; Gal. 5:16-17). Amalek was defeated by Israel through the supply of the manna (ch. 16) and the living water (vv. 1-6) and by the lifting up of Moses’ hands and the fighting of Joshua. Likewise, we are victorious over the flesh by eating and drinking Christ as our life supply and by praying with the interceding Christ and putting the flesh to death with Christ as the fighting Spirit (Rom. 8:13 and note Rom. 8:132a; Gal. 5:24 and note Gal. 5:24:2).
