have given it to Joshua as commander, to be borne by him in front of the combatants, or else have entrusted it to Aaron, who had performed the miracles in Egypt, that he might carry it at their head. The pure reason why Moses did not do this, but withdrew from the field of battle to lift up the staff of God upon the summit of a hill, and to secure the victory by so doing, is to be found in the important character of the battle itself. As the heathen world was now commencing its conflict with the people of God in the persons of the Amalekites, and the prototype of the heathen world, with its hostility to God, was opposing the nation of the Lord, that had been redeemed from the bondage of Egypt and was on its way to Canaan, to contest its entrance into the promised inheritance; so the battle which Israel fought with this foe possessed a typical significance in relation to all the future history of Israel. It could not conquer by the sword alone, but could only gain the victory by the power of God, coming down from on high, and obtained through prayer and those means of grace with which it had been entrusted. The means now possessed by Moses were the staff, which was, as it were, a channel through which the powers of omnipotence were conducted to him. In most cases he used it under the direction of God; but God had not promised him miraculous help for the conflict with the Amalekites, and for this reason he lifted up his hands with the staff in prayer to God, that he might thereby secure the assistance of Jehovah for His struggling people. At length he became exhausted, and with the falling of his hands and the staff he held, the flow of divine power ceased, so that it was necessary to support his arms, that they might be kept firmly directed upwards (אמוּנה, lit., firmness) until the enemy was entirely subdued. And from this Israel was to learn the lesson, that in all its conflicts with the ungodly powers of the world, strength for victory could only be procured through the incessant lifting up of its hands in prayer. “And Joshua discomfited Amalek and his people (the Amalekites and their people) with the edge of the sword” (i.e., without quarter. See Gen 34:26).
Verse 14
As this battle and victory were of such significance, Moses was to write it for a memorial בּסּפר, in “the book” appointed for a record of the wonderful works of God, and “to put it into the ears of Joshua,” i.e., to make known to him, and
