Bible Notes Online - Deuteronomy 3 - ESV
Commentary

v2: God had promised victory; compare 2.30-31, but contrast 1.42, when the Lord was not amongst the people, and they suffered defeat. victory is only gained when God is with us; we dare not go forward in presumption and self-confidence. We must constantly seek His will and direction.

v4-5: The task described here was not insignificant; there were 60 walled cities, in addition to many unwalled villages. God is seen to be greater than any human defence.

v6: The victory was thorough, as in 2.34-35.

The ruthlessness of the Israelites may give us concern. However, firstly God's command was to utterly destroy these people. Secondly, when the Israelites had joined with another people, after even a short time, they had grown corrupt; see for example Num 25.

It is sobering to think that we all deserve death at the hand of God; none are worthy, since none have done good.

v8: The two Kings of the Amorites were Sihon and Og; Num 21.21-35 narrates the victories.

v11: Og was a giant, one of those feared by the Israelites. It is therefore significant that Moses mentioned this. Those feared by the Israelites could indeed be defeated.

v12-17: The land given to the 2½ tribes east of the Jordan. Moses mentioned that he, not the Lord, gave the land to these tribes, see v12, 13, 15, 16.

The facts of their inheritance were related without mentioning their rebellion; at this stage, Moses did not want to stir up fresh dissent, nor discourage the people.

v18-20: Moses did, however, note the responsibility on the 2½ tribes to support the other tribes as they invaded Canaan. Here he reminded them of this responsibility, since they occupied land defeated by the whole Israelite army.

v21: The past victories were to be an encouragement to Joshua, the new leader of the Israelites.

v22: The Lord fights for His people; again this was an encouragement for Joshua, since he could trust God for future victories also. God's faithfulness and power remain available to all who trust in Him.

v24: Moses knew the truth that there was only One true God; no other god could do what He had done.

v25-28: Moses requested that God might show him the land of Canaan. But he was forbidden from entering because of his anger.

v29: The people stayed in the valley opposite Beth Peor; see 4.46.
