Babylonian Talmud, Tractate Shabbat 77b

תלמוד בבלי מסכת שבת דף עז עמוד ב
2 ב
אמר רב יהודה אמר רב: כל מה שברא הקדוש ברוך הוא בעולמו לא ברא דבר אחד לבטלה. ברא שבלול לכתית, ברא זבוב - לצירעה, יתוש - לנחש, ונחש - לחפפית, וסממית - לעקרב.
Rab Judah said in Rab's name: Of all that the Holy One, blessed be God, created in God's world, God did not create a single thing without purpose. [Thus] God created the snail as a remedy for a scab; the fly as an antidote to the hornet[‘s sting]; the mosquito [crushed] for a serpent[‘s bite]; a serpent as a remedy for an eruption. and a [crushed] spider as a remedy for a scorpion[‘s bite]. [Soncino Translation]
