נ֤וֹדַ֨ע ׀ יְהוָה֮ מִשְׁפָּ֪ט עָ֫שָׂ֥ה בְּפֹ֣עַל כַּ֭פָּיו נוֹקֵ֣שׁ רָשָׁ֑ע הִגָּי֥וֹן סֶֽלָה׃
גאָט איז באַװוּסט געװאָרן, ער האָט אַ משפּט געטאָן –אין דעם װערק פֿון זײַנע הענטאיז געשטרױכלט געװאָרן דער רָשע. הִגָיון סֶלָה.
Rashi
The Lord is known All this is part of the praise: The Lord is known to the creatures; [it is known] that He governs and rules and wreaks vengeance upon His enemies, for He performs justice upon them, “justice” in French.
Radak
The Lord hath made Himself known: – Now the Lord has made Himself known in this war, for Israel had conquered them with but little strength and power, compared with theirs; and they would not have been able to conquer them except the Lord had fought for Israel.
