Dewarim 8:2 Kommentar: Rashi, Ramban, Sforno & Rashbam

התשמר מצותו [THAT HE MIGHT KNOW WHAT WAS IN THY HEART] WHETHER THOU WOULDST KEEP HIS COMMANDMENTS — viz., the commandment that ye should not put Him to the test, and that you should not doubt Him (i.e. His ways).

AND THOU SHALT REMEMBER ALL THE WAY WHICH THE ETERNAL THY G-D HATH LED THEE etc. He is stating that you can realize that in the observance of the commandments is entailed the perfect good and there will not be the righteous forsaken, nor his seed begging bread,⁵⁸Psalms 37:25. for G-d supported you in the wilderness with the performance of a great miracle because you followed after His commandments. I have already explained⁵⁹Exodus 16:4 (Vol.II, pp. 221-222). in the section of the manna [the verse before us], that He might afflict thee, to try thee, to know what was in thy heart, whether thou wouldest keep His commandments, or no, for [the manna itself] was a great trial to them. They did not know what counsel to adopt for themselves when they entered the great wilderness, a place of no food, and they had none of the manna [in reserve because it could not be stored from day to day] but each day’s portion came down on its day, and as the sun waxed hot, it melted,⁶⁰Ibid., Verse 21. although they hungered mightily after it. All this they did to keep the commandment of G-d, to follow as He commanded. Now G-d could have led them through the [populated] cities that were around them, but instead He brought them into this trial [of never having any food in reserve] for He knew that as a result [of this experience] they would keep His commandments forever.

וזכרת את כל הדרך, during which He gave you bread to eat, clothes to wear, by supernatural means.
