(21, 22) I commanded Joshua at that time. . . . Thine eyes have seen.--"Thine eyes are the witnesses of all," &c. The conquest of Sihon and Og, as well as that of Amalek, was to be impressed upon Joshua (comp. Exodus 17:14) as a precedent for his encouragement, and also for his instruction. It is remarkable that no details are given us of the battles against Sihon and Og, or of the capture of the cities, except in Joshua 12:6, "Them did Moses the servant of the Lord smite." We see the reflection of Moses' campaign, which is unwritten, in the recorded campaigns of Joshua. The peculiar form of the sentence, "Thine eyes are they that see," may also serve to remind us of the fact, that though the Law was given by Moses, no eye saw its full breadth and grasp until it came into the hand of Jesus, the antitype of Joshua.
Verses 21, 22.- Joshua appointed as Mosessuccessor in the leadership. Verse 21. - At that time, i.e. after the conquest of the land on the east of the Jordan (see Numbers 27:12, etc.). Thine eyes have seen, etc. Joshua was directed to what he had himself witnessed, what his own eyes had seen, in the destruction of Sihon and Og and their hosts, that he might be encouraged to go forward in the course to which he had been called; and the people are reminded of this, that they may keep in mind what God had done for Israel, and may without fear follow Joshua as their leader to the conquest of Canaan (comp. Deuteronomy 31:23).
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.
And I commanded Joshua at that time,.... After the conquest of the two kings, and the assignment of their countries to the above tribes; and after Moses had it made known to him that he should quickly die, and Joshua should be his successor; then, by the direction of God, he gave him the following charge:
saying, thine eyes have seen all that the Lord your God hath done unto these two kings; Sihon and Og; how their kingdoms were taken from them, and given to Israel, and they slain with the sword; this Joshua was an eyewitness of, and was, no doubt, greatly concerned in the battles with them, being the general in the Israelitish armies; at least this was sometimes his post, and he cannot be thought to have been unemployed in these wars:
so shall the Lord do unto all the kingdoms whither thou passest; all the kingdoms in the land of Canaan, where there were many, thirty one at least; these would be all conquered and put into the hands of the Israelites, and their kings slain.
