Musar zu Jehoschua 2:6

(Devarim 26:17): "The L-rd did you single out this day to be to you as a G-d, and to walk in His ways, and to keep His statutes, and His mitzvoth, and His judgments, and to heed His voice." From this verse we learn the greatness of strengthening oneself to walk in the ways of the traits of the Holy One Blessed be He, to be merciful, gracious, and the like. For Scripture mentioned this quality ["to walk in His ways"] before keeping the statutes, the mitzvoth, and the judgments, whereby we infer that it takes precedence to the others [(as we find in Berachoth 41b on the verse that speaks in praise of Eretz Yisrael (Devarim 8:8): "a land of wheat, barley, grapevine, etc." — "That which precedes (in the verse) precedes for the blessing."] And one must greatly strengthen oneself in this — whence we learn in our instance to guard greatly against the issur of lashon hara. For this is one of the ways of the traits of the Holy One Blessed be He, as our sages of blessed memory said (Sanhedrin 43b) concerning the deed of Achan, who violated the ban, because of which Israel was defeated in the war. (Joshua 2:6): "And he [Joshua] fell on his face to the ground before the ark of the L-rd… (10): And the L-rd said to Joshua: 'Arise, why do you fall on your face… they have also stolen; they have also denied… (12): I will not be with you if you do not destroy the cherem [(the forbidden property] from your midst.'" Joshua said to Him: "Who has sinned?", to which He answered: "Am I a slanderer? Go and cast lots and it will be known to you." Even for something that it was a mitzvah to clarify, such as the act of Achan, where they were obliged to destroy the cherem, even so, since it could come to light of itself, it should not be spoken.
