17 As well as the Arabah, with the river Jordan as their limit, from Chinnereth to the Salt Sea, under the slopes of Pisgah to the east. 18 At that time I gave you orders, saying, The Lord has given you this land for your heritage: all the men of war are to go over armed before your brothers the children of Israel. 19 But your wives and your little ones and your cattle (for it is clear that you have much cattle) may go on living in the towns I have given you; 20 Till the Lord has given rest to your brothers as to you, and till they have taken for themselves the land which the Lord your God is giving them on the other side of Jordan: then you may go back, every man of you, to the heritage which I have given you.

21 And I gave orders to Joshua at that time, saying, Your eyes have seen what the Lord your God has done to these two kings: so will the Lord do to all the kingdoms into which you come. 22 Have no fear of them, for the Lord your God will be fighting for you.

Moses Not Permitted to Enter Canaan

23 And at that time I made request to the Lord, saying, 24 O Lord God, you have now for the first time let your servant see your great power and the strength of your hand; for what god is there in heaven or on earth able to do such great works and such acts of power? 25 Let me go over, O Lord, and see the good land on the other side of Jordan, and that fair mountain country, even Lebanon. 26 But the Lord was angry with me because of you and would not give ear to my prayer; and the Lord said to me, Let it be enough, say no more about this thing. 27 Go up to the top of Pisgah, and turning your eyes to the west and the north, to the south and the east, see the land with your eyes: for you are not to go over Jordan.

Commentary on Deuteronomy 3:12-20

(Read Deuteronomy 3:12-20)

This country was settled on the Reubenites, Gadites, and half the tribe of Manasseh: see Numbers 32. Moses repeats the condition of the grant to which they agreed. When at rest, we should desire to see our brethren at rest too, and should be ready to do what we can towards it; for we are not born for ourselves, but are members one of another.

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.
