וַיִּתְעָרְב֥וּ בַגּוֹיִ֑ם וַֽ֝יִּלְמְד֗וּ מַֽעֲשֵׂיהֶֽם׃
열방과 섞여서 그 행위를 배우며
Pirkei Avot
Abtalion used to say: Sages be careful with your words, lest you incur the penalty of exile, and be carried off to a place of evil waters, and the disciples who follow you drink and die, and thus the name of heaven becomes profaned.
