They shall abundantly utter the memory of thy great goodness - Hebrew, The memory of the greatness of thy goodness they will pour forth. The word rendered “abundantly utter” means to bud forth, to gush out, to flow, as a fountain. Proverbs 18:4; Proverbs 1:23; Proverbs 15:2, Proverbs 15:28. It is applied to words as poured forth in praise. The meaning is, that the heart is full, as a fountain is full of water, and that it naturally overflows, or seeks to discharge itself. The thought of the goodness of God fills the heart, and makes it overflow with gratitude.
And shall sing of thy righteousness - They shall shout for joy at the displays of thy justice; at the manifestations of thy righteous character.
