Sforno on Numbers 14:9/ספורנו על במדבר י״ד:ט׳

1אך בה' אל תמרודו, if you indeed want the soil of this land to correspond to your fond hopes of it, it is incumbent upon you not to rebel against G’d, something you have been told about repeatedly. (compare Deuteronomy 11,13-14 lines we recite at least twice daily.)

2ואתם אל תיראו, if you do not rebel against the Lord He will bring you there and you will have no reason to be afraid of anything, for they are our bread, we have seen with our own eyes that they did not even dare to attack the 12 of us. 40 years later Rachav the innkeeper of Jericho testified that the people were still terribly afraid of the Israelites, none of them summoning enough spirit to go to war against this people. (Joshua 2,11) סר צלם מעליהם, we have seen that they have decided to abandon all armed resistance, reminiscent of what we read in Kings II 7,15 when the armies of Aram had abandoned all their equipment in headlong flight, when they had merely imagined that they were being attacked.
