As the Hebrews triumphed when Moses was reaching his hands toward heaven and interceding in their behalf, so the Israel of God prevail when they by faith take hold upon the strength of their mighty Helper. Yet divine strength is to be combined with human effort. Moses did not believe that God would overcome their foes while Israel remained inactive. While the great leader was pleading with the Lord, Joshua and his brave followers were putting forth their utmost efforts to repulse the enemies of Israel and of God.

Ligesom hebræerne sejrede, når Moses rakte sine hænder op mod himmelen og gik i forbøn for dem, således vil Guds Israel vinde sejr, når de i tro griber fat i deres mægtige hjælper. Men den guddommelige kraft må forenes med menneskenes egne anstrengelser. Moses troede ikke, at Gud ville besejre fjenderne, mens Israel selv var uvirksomme. Mens deres store leder bad til Herren, gjorde Josua og hans tapre ledsagere deres yderste for at slå Guds Israels fjender tilbage.
