זֵ֣כֶר רַב־טוּבְךָ֣ יַבִּ֑יעוּ וְצִדְקָתְךָ֥ יְרַנֵּֽנוּ׃
저희가 주의 크신 은혜를 기념하여 말하며 주의 의를 노래하리이다
Rashi
Of the remembrance of Your abundant goodness they will speak i.e., one generation to another generation. and they will speak of Your might to each other, saying, “It is good for us to make known to the children of men His mighty deeds and the glory of the majesty of the kingdom of the Holy One, blessed be He.” (I found.)
Radak
The fame of Thy great goodness: "Great" is a noun, not an adjective, as if it said, "the greatness of Your goodness."
