Deuteronomy 29:17

פן יש בכם means PERHAPS (שמא = פן) THERE IS AMONG YOU, אשר לבבו פנה היום [A MAN …] WHOSE HEART TURNETH AWAY THIS DAY from accepting the covenant upon himself, שרש פרה ראש ולענה [PERHAPS THERE IS AMONG YOU] A ROOT THAT IS FRUITFUL IN POISONOUS HERB AND WORMWOOD — i.e. a root that brings forth herbs bitter as wormwood-plants, which are very bitter. The meaning is: Lest there be a man or woman or family or tribe that fruitfully produces and increases wickedness in your midst.

פֶּן־יֵ֣שׁ בָּ֠כֶ֠ם אִ֣ישׁ אֽוֹ־אִשָּׁ֞ה א֧וֹ מִשְׁפָּחָ֣ה אוֹ־שֵׁ֗בֶט אֲשֶׁר֩ לְבָב֨וֹ פֹנֶ֤ה הַיּוֹם֙ מֵעִם֙ יְהֹוָ֣ה אֱלֹהֵ֔ינוּ לָלֶ֣כֶת לַעֲבֹ֔ד אֶת־אֱלֹהֵ֖י הַגּוֹיִ֣ם הָהֵ֑ם פֶּן־יֵ֣שׁ בָּכֶ֗ם שֹׁ֛רֶשׁ פֹּרֶ֥ה רֹ֖אשׁ וְלַעֲנָֽה׃

lest there should be among you man, or woman, or family, or tribe, whose heart turns away this day from the Lord our God, to go and serve the gods of these nations; lest there should be among you a root that bears gall and wormwood;
