John Gill Commentary Psalms 145:12

"To make known to the sons of men his mighty acts, And the glory of the majesty of his kingdom." — Psalms 145:12 (ASV)

To make known to the sons of men his mighty acts
As in (Psalms 145:4) ; the acts of his power in providence and grace; in the salvation of his people, and the destruction of their enemies; which, with others, are made known in the ministry of the word, to those who were strangers to them, to those without the church, who wait at Wisdom's gates, and at the posts of her door; Aben Ezra interprets it of little ones, or children that knew them not, whose parents would make them known to them: rather it designs the common people, instructed by the word and the ministers of it:

and the glorious majesty of his kingdom ;
the majesty of him as King, and the glory of his kingdom, (Psalms 145:5Psalms 145:11) ; and the perpetuity of it, as follows.
