Commentary for Numbers 14:9

אל תמרדו [ONLY] REBEL NOT YE [AGAINST THE LORD], and consequently ואתם אל תיראו YOU WILL NOT HAVE TO FEAR [THE PEOPLE OF THE LAND].

ONLY REBEL NOT AGAINST THE ETERNAL. This means that [Moses and Aaron told the people]: “Your being afraid [to go up] because of the strength of the people that dwell in the Land is [in itself] a rebellion against the Glorious Name,¹⁰¹Deuteronomy 28:58. for it was not because of your [own] strength that you came out of Egypt, but it was the hand of the Eternal that hath dealt wondrously with you.¹⁰²Joel 2:26. And He has assured you that He will drive them out from before you; if so, believe [in Him] and you will succeed.” They [Moses and Aaron] continued: neither fear ye the people, for they are bread for us, meaning that “even in the natural course of events and through normal methods of [warfare as practiced in] the world, they will fall before us, for the fear of us has overcome them and they will let us consume them like bread.”

אך 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.)
