דברים כ״ג:ד׳-ז׳

לא יבא עמוני. לֹא יִשָּׂא יִשְׂרְאֵלִית:

An Ammonite may not enter. He may not marry an Israelite woman.

על דבר. עַל הָעֵצָה שֶׁיָּעֲצוּ אֶתְכֶם לְהַחֲטִיאֲכֶם:

Because of the matter. Because of their advice concerning you, to incite you to sin [as written in the affair of Bilam].

בדרך. כְּשֶׁהֱיִיתֶם בְּטֵרוּף (ספרי):

On the way. When you were harried.

לא תדרש שלמם. מִכְּלָל שֶׁנֶּאֱמַר עִמְּךָ יֵשֵׁב בְּקִרְבְּךָ יָכוֹל אַף זֶה כֵּן, תַּ"לֹ לא תדרש שלמם (עי' ספרי):

Do not pursue their peace. By inference from what is said, “He may remain with you, in your midst,” perhaps this one as well? The Torah therefore teaches, “Do not pursue their peace.”
