זֵ֣כֶר רַב־טוּבְךָ֣ יַבִּ֑יעוּ וְצִדְקָתְךָ֥ יְרַנֵּֽנוּ׃
Ipahahayag nila ang alaala ng Iyong dakilang kabutihan, at aawitan nila nang may galak ang Iyong katuwiran.
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."
Radak
They shall utter: They shall speak, as in "the lips shall speak."
