Shemot
וַיֹּאמֶר הַשְׁלִיכֵהוּ אַרְצָה, וַיַּשְׁלִכֵהוּ אַרְצָה וַיְהִי לְנָחָשׁ; וַיָּנָס מֹשֶׁה, מִפָּנָיו
And He said: 'Cast it on the ground.' And he cast it on the ground, and it became a serpent; and Moses fled from before it ... Shemot 4:3
Moses fled.
Snake is a totem of Divine Feminine power, of Goddess. Importantly, Snake magic is heavy magic, and not for the weak minded. Snake medicine witches and magicians are those whose experiences involve contact with poisons (physical, emotional and spiritual) and the transmutation and transformation of those poisons into something extraordinarily beautiful. As Snake swallows its food whole, so too do Snake witches take in Wisdom and Understanding with wholeness to create perfect Knowledge.
