אִם־לֹ֣א יָ֭שׁוּב חַרְבּ֣וֹ יִלְט֑וֹשׁ קַשְׁתּ֥וֹ דָ֝רַ֗ךְ וַֽיְכוֹנְנֶֽהָ׃
פֿאַר װאָר, ער שלײַפֿט נאָכאַנאַנד זײַן שװערד, ער שפּאַנט זײַן בױגן און שטעלט אים אָן.
Rashi
If he does not repent [i.e., if] the wicked [does not repent] of his wickedness.
Radak
If he will not turn (and) whets his sword: – We have already explained the meaning as depending upon (the clause) above. And he says: when he (the wicked man) will not turn and whets his sword to slay me.
Rashi
He will whet His sword The Holy One, blessed be He, [will whet His sword] for him. ילטוש means forbira in Old French, to polish, furbish; and He will tread His bow.
