וַיִּתְעָרְב֥וּ בַגּוֹיִ֑ם וַֽ֝יִּלְמְד֗וּ מַֽעֲשֵׂיהֶֽם׃
I pomieszali się z narodami, i nauczyli się spraw ich.
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.
