23 At that time, too, I entreated the Lord, saying: 24 "O Lord God, you have only begun to show your servant your greatness and your might; what god in heaven or on earth can perform deeds and mighty acts like yours! 25 Let me cross over to see the good land beyond the Jordan, that good hill country and the Lebanon." 26 But the Lord was angry with me on your account and would not heed me. The Lord said to me, "Enough from you! Never speak to me of this matter again! 27 Go up to the top of Pisgah and look around you to the west, to the north, to the south, and to the east. Look well, for you shall not cross over this Jordan. 28 But charge Joshua, and encourage and strengthen him, because it is he who shall cross over at the head of this people and who shall secure their possession of the land that you will see."

Commentary on Deuteronomy 3:21-29
(Read Deuteronomy 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.
