Chapter 3

Next the people fight and defeat Og, King of Bashan, another king of the Amorites.  They take 60 walled cities and all the unwalled villages.  As with Sihon, it seems to me these cities are razed to the ground.  I don't think Israel moved in and lived in these cities.  They were "devoted to destruction".  There is a note in MSB on vs 6 where the phrase "devoted to destruction" is used.  It says "That is, set apart (devoted) as an offering to the Lord (for destruction):..."   They kill men, women, and children, but keep the livestock.  Og was the last of the Rephaim.  His bed was made of iron, and 9 cubits long, 13.5 feet.  He was a giant, and he and his people were defeated by Israel.

Reuben, Gad, and Manasseh take their possession on the east side of Jordan because it is good for livestock.  Then this verse:

19 Only your wives, your little ones, and your livestock (I know that you have much livestock) shall remain in the cities that I have given you, [Deu 3:19 ESV]

This implies that the cities in the lands East of the Jordan were intact - at least some were.  No...Numbers 32:16 says that the tribes who took possession of these lands to the East of the Jordan built their own cities:

16 Then they came near to him and said, "We will build sheepfolds here for our livestock, and cities for our little ones, [Num 32:16 ESV]

Though Moses has been told he cannot enter Canaan, he asks God to let him go over and just see it.  In fact, in ESV it says Moses pleaded with God.  These verses:

23 "And I pleaded with the LORD at that time, saying, ... 25 Please let me go over and see the good land beyond the Jordan, that good hill country and Lebanon.' [Deu 3:23, 25 ESV]

God says no.  A pretty emphatic no:

26 But the LORD was angry with me because of you and would not listen to me. And the LORD said to me, 'Enough from you; do not speak to me of this matter again. [Deu 3:26 ESV]

But God lets him see it from a mountain on the east of Jordan.  God says Joshua will lead the people into Canaan.  Moses tells the people he can't go over because of them.  Moses' sin was striking the rock instead of just speaking to it.  Not sure how this is "because of them".  (MSB says that because of Israel's sin, God's punishment for them was that they could not enter the land.  They lacked faith that God could do what he said.   Moses' sin in striking instead of obeying God's command to speak to the rock, was the same sin - lack of faith.  Therefore, because Israel's punishment was to be kept from the land, Moses was also kept out.  Because of their punishment, he is punished the same way, for the same sin.)
