This instance was to be a lesson to all Israel to the close of time that God is the strength of His people. When Israel triumphed, Moses was reaching his hands toward heaven and interceding in their behalf; so when all the Israel of God prevail, it is because the Mighty One undertakes their case and fights their battles for them. Moses did not ask or believe that God would overcome their foes while Israel remained inactive. He marshals all his forces and sends them out as well prepared as their facilities can make them, and then he takes the whole matter to God in prayer. Moses on the mount is pleading with the Lord, while Joshua with his brave followers is below, doing his best to meet and repulse the enemies of Israel and of God. (4T 531.1) MC VC

That prayer which comes forth from an earnest, believing heart is the effectual, fervent prayer that availeth much. God does not always answer our prayers as we expect, for we may not ask what would be for our highest good; but in His infinite love and wisdom He will give us those things which we most need. Happy the minister who has a faithful Aaron and Hur to strengthen his hands when they become weary and to hold them up by faith and prayer. Such a support is a powerful aid to the servant of Christ in his work and will often make the cause of truth to triumph gloriously. (4T 531.2) MC VC

After the transgression of Israel in making the golden calf, Moses again goes to plead with God in behalf of his people. He has some knowledge of those who have been placed under his care; he knows the perversity of the human heart and realizes the difficulties with which he must contend. But he has learned from experience that in order to have an influence with the people he must first have power with God. The Lord reads the sincerity and unselfish purpose of the heart of His servant and condescends to commune with this feeble mortal, face to face, as a man speaks with a friend. Moses casts himself and all his burdens fully upon God and freely pours out his soul before Him. The Lord does not reprove His servant, but stoops to listen to his supplications. (4T 531.3) MC VC
