נְֽ֭נַתְּקָה אֶת־מֽוֹסְרוֹתֵ֑ימוֹ וְנַשְׁלִ֖יכָה מִמֶּ֣נּוּ עֲבֹתֵֽימוֹ׃
לאָמיר צערײַסן זײערע בינד, און אַראָפּװאַרפֿן פֿון אונדז זײערע שטריק.
Rashi
Let us break their bands Deronproms lor koyongles in Old French (as in Jer. 27:2). These are the bands with which the yoke is tied.
Radak
Let us break their bands asunder: – They were saying: “Let us break the bands of Israel and their league (lit. binding) in which they have bound themselves and agreed to make David king.” For there had elapsed seven years in which Israel as a whole had not agreed about him to make him king, and now when they had all agreed about him the Philistines said “let us break their bands asunder.”
Ibn Ezra
Let us break their cords (nenattekah et mosroteimo): [The word mosroteimo - their cords/bonds] is from the root musar (מוּסָר - discipline, bond, instruction).
