"You have given him the desire of his heart. And what is the permission of his lips? That when he says, "Let such and such a province rebel," his word is fulfilled, as he says, "Let Gobai go and destroy it" (Isaiah 10:6). Or if he says, "Let the Apharachites rebel against you," his word is fulfilled, as he says, "Let the angel of death go and destroy them" (ibid. verse 5). And his permission of his lips, when he decrees, his words are established."
"When we advance with good blessings, Rabbi Yehuda says, the blessings of Moses, which are called good, as it says, 'And she saw that he was good' (Exodus 2:2). The Rabbis say, the blessings of the Torah, as it says, 'For I give you good instruction; do not forsake my Torah' (Proverbs 4:2). Chayim asked you: Rabbi Yochanan said, God asked three people in Psalm, 'Ask me and I will grant it to you,' etc. Why were they agitated? Rabbi Berachya said, even those who descended to the Pit, they were still alive. They are Korach and his congregation, Ahithophel, and Doeg. 'Great is His glory in Your deliverance' (Psalms 21:6), 'The splendor of the disciple' (Pirkei Avot 6:3), as it is said, 'And You placed Your splendor upon him' (Psalms 21:6). Your splendor, but not all of Your splendor. And where was it given to Joshua? Rabbi Yehudah said, it was given to him at the Jordan. In the case of Moses, it is written, 'And they were afraid to come near him' (Exodus 34:30), and in the case of Joshua, it is written, 'And they were afraid of him as they were afraid of Moses' (Joshua 4:14)."
