Kabbalah for Numbers 21:27

If man was mindful of this knowledge sinners wouldn't exist, temptation wouldn't even wield power, similar to its irrelevance to angels. G-d wanted man to conquer or to be conquered via temptation and his subsequent choices, and therefore gave us this knowledge that remains latent as a flame is within a coal. Our sages of blessed memory have said (Bava Batra 78b): "Wherefore they who speak in similes (Hamoshlim) say, Come to Ḥeshbon..."(Bamidbar 21:27), 'Hamoshlim' (who speak in similies) - refers to those that control their inclination, "Bo'oo Heshbon (Come to Heshbon) - Come and let us calculate the account (heshbono) of the world! Those that do not conrtol their inclination will never prioritize this - However, those that do control their inclination will practice this and teach others to act as well.
