Albert Barnes Commentary Psalms 145:4

"One generation shall laud thy works to another, And shall declare thy mighty acts." — Psalms 145:4 (ASV)

One generation shall praise thy works...—shall praise You on account of Your works or Your doings. That is, Your praise shall be always kept up on the earth. See the notes at Isaiah 38:19; notes at Psalm 19:2.

One generation shall transmit the knowledge of Your works to another by praise—by hymns and psalms recording and celebrating Your praise. Successive generations of people shall take up the language of praise, and it shall thus be transmitted to the end of time.

And shall declare thy mighty acts—Your works of strength or power. God’s greatness—His infinity—is in itself a just ground of praise, for we should rejoice that there is One Infinite Eternal Being; and as all that greatness is employed in the cause of truth, of law, of good order, of justice, of kindness, of mercy, it should call forth continued praise in all parts of His dominions.
