17 The western boundary was the Jordan River in the Arabah all the way from the Kinnereth (the Sea of Galilee) to the Sea of the Arabah (the Salt Sea or Dead Sea) at the base of the slopes of Mount Pisgah on the east. 18 I commanded you at that time, "God, your God, has given you this land to possess. Your men, fit and armed for the fight, are to cross the river in advance of their brothers, the People of Israel. 19 Only your wives, children, and livestock (I know you have much livestock) may go ahead and settle down in the towns I have already given you 20 until God secures living space for your brothers as he has for you and they have taken possession of the country west of the Jordan that God, your God, is giving them. After that, each man may return to the land I've given you here."
21 I commanded Joshua at that time, "You've seen with your own two eyes everything God, your God, has done to these two kings. God is going to do the same thing to all the kingdoms over there across the river where you're headed. 22 Don't be afraid of them. God, your God, - he's fighting for you."
23 At that same time, I begged God: 24 "God, my Master, you let me in on the beginnings, you let me see your greatness, you let me see your might - what god in Heaven or Earth can do anything like what you've done! 25 Please, let me in also on the endings, let me cross the river and see the good land over the Jordan, the lush hills, the Lebanon mountains." 26 But God was still angry with me because of you. He wouldn't listen. He said, "Enough of that. Not another word from you on this. 27 Climb to the top of Mount Pisgah and look around: look west, north, south, east. Take in the land with your own eyes. Take a good look because you're not going to cross this 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.
