출애굽기 4:31의 Musar

And they were redeemed because of their faith, as it is written: "And the people believed" (Exod. 4:31). The Sages said of this verse, "Each one who takes upon himself one commandment with faith is worthy that the Holy Spirit shall dwell upon him." And the exiles are brought back through the merit of faith as it is said : "Look forth from the summit of Amanah (Faith)" (Eccl. 4:8). And it says further : "And I shall betroth thee to me with faith" (Hosea 2:22).

(Shemoth 4:6): "And the L-rd said to him again: 'Put your hand into your bosom, etc.'" (see Rashi). In this instance, He also intimated to him that he had spoken lashon hara, and that because of this he would be stricken with leprosy. And even though in the beginning, he had already received his punishment in dread of the serpent, this ["Put your hand into your bosom, etc."] was because of the second thing he had said, i.e., "And they will not hearken to my voice." And, in truth, it was not so [i.e., that they did not hearken], it being written afterwards (Ibid. 31): "And the people believed, and they hearkened, etc."
