Verse 24. - O Lord God: O Lord Jehovah. For what God, etc. (comp. Exodus 15:11; Psalm 86:8; Psalm 89:6; Psalm 113:5, etc.). "The contrast drawn between Jehovah and other gods does not involve the reality of heathen deities, but simply presupposes a belief in the existence of other gods, without deciding as to the truth of that belief" (Keil).

3:21-29 Moses encouraged Joshua, who was to succeed him. Thus the aged and experienced in the service of God, should do all they can to strengthen the hands of those who are young, and setting out in religion. Consider what God has done, what God has promised. If God be for us, who can be against us, so as to prevail? We reproach our Leader if we follow him trembling. Moses prayed, that, if it were God's will, he might go before Israel, over Jordan into Canaan. We should never allow any desires in our hearts, which we cannot in faith offer up to God by prayer. God's answer to this prayer had a mixture of mercy and judgment. God sees it good to deny many things we desire. He may accept our prayers, yet not grant us the very things we pray for. It God does not by his providence give us what we desire, yet if by his grace he makes us content without, it comes to much the same. Let it suffice thee to have God for thy Father, and heaven for thy portion, though thou hast not every thing thou wouldst have in the world. God promised Moses a sight of Canaan from the top of Pisgah. Though he should not have the possession of it, he should have the prospect of it. Even great believers, in this present state, see heaven but at a distance. God provided him a successor. It is a comfort to the friends of the church of Christ, to see God's work likely to be carried on by others, when they are silent in the dust. And if we have the earnest and prospect of heaven, let these suffice us; let us submit to the Lord's will, and speak no more to Him of matters which he sees good to refuse us.O Lord God, thou hast begun to show thy servant thy greatness and thy mighty hand,.... To give a specimen of the greatness of his power in subduing the two kings and their kingdoms, and delivering them up into the hands of the Israelites. Moses had seen instances of the mighty power of God in Egypt, at the Red sea, and in the wilderness; but this was the beginning of his power, in vanquishing the Canaanites, and putting their land into the possession of the Israelites, as he had promised; of which the Amorites were a part, and a principal nation of them: and thus God, when he begins a work of grace upon the soul of man, begins to show the exceeding greatness of his power, and which is further exerted in carrying it on, and bringing it to perfection:

for what God is there in heaven or in earth that can do according to thy works, and according to thy might? here Moses speaks according to the notion of Heathens, who supposed there were other gods in heaven and in earth besides the true God; and upon this supposition observes, let there be as many as they will, or can be imagined, there is none of them like the Lord God of Israel for power and might; or are able to do such works as he has done, in nature, in the creation of all things out of nothing, in providence, in supporting what he has made, and in governing the world; and in those amazing instances of his power, in bringing down judgments upon wicked men, kings, and kingdoms; and in the deliverance of his own people from them, and putting them and their kingdoms into the possession of them; which were the wondrous works of might Moses had in view, and a sense of which was impressed on his mind at this time.
