וְהַנָּבִ֤יא כִֽי־יְפֻתֶּה֙ וְדִבֶּ֣ר דָּבָ֔ר אֲנִ֤י יְהוָה֙ פִּתֵּ֔יתִי אֵ֖ת הַנָּבִ֣יא הַה֑וּא וְנָטִ֤יתִי אֶת־יָדִי֙ עָלָ֔יו וְהִ֨שְׁמַדְתִּ֔יו מִתּ֖וֹךְ עַמִּ֥י יִשְׂרָאֵֽל׃
先知若受了迷惑而說了話，是我永恆者讓那先知受了迷惑；我必向他伸手，將他從我的百姓以色列中除滅。
Rashi
have enticed I opened a doorway for him to [do] whatever he wishes. And from here we can learn that if one wishes to defile himself, they open [a door] for him.
