잠언 1:11의 Halakhah

And how much must one strengthen himself not to give these people an opening in the beginning; that is, not to argue with them, but to strengthen himself greatly not to associate himself with them at all, as it is written (Mishlei 1:11-16): "If they say, 'Come with us… keep your feet from their path. For their feet run to evil, etc.'" And Chazal have said in Eduyoth 5:6: "Better that a man be called a fool all of his days and not be wicked one moment before the L–rd." "called a fool" is stated because of the matter discussed there; but in truth, it befits a man to commit folly, even actively, so that the epithet "wicked" not apply to him, even for one moment, above. As we find in Scripture (viz. I Samuel 21:16) that David made himself [act] like a fool in the house of Avimelech so that he not fall into his hands. How much more so [should one follow this stratagem if necessary] for the sake of the King of kings, the Holy One Blessed be He! And (Chullin 5b): "(Psalms 36:7): 'Man and beast do You save, O L–rd' – these are men who are wise in knowledge, but who make themselves [act foolish] like a beast [for the sake of the L–rd]." And see Berachoth 19b: "If one finds sha'atnez in his garment, etc."
