Likutei Moharan 20:7/ליקוטי מוהר"ן כ׳:ז׳

17. And know! the spiritual forces which are created from the letters of the Torah originated <by this sage>—they are bona fide angels. They receive the power from Edom in order to punish the wicked with the sword and with death. And they are created in the concept of (Psalms 68:12), “The Lord gives the word, the heralds are a mighty host.” They punish the wicked, as in (ibid. 91:11, 13), “He will charge His angels on your behalf…. Upon the lion and the viper you will tread.”
