Adam Clarke on Psalms 145:10

All thy works shall praise thee - The God who is good to all.

Thy saints - חסידיך chasideycha, thy compassionate ones; those who are partakers of thy great mercy, Psa 145:8. These shall bless thee, because they know, they feel, that thou willest the salvation of all. The dark, the gloomy, the hard-hearted, the narrow-minded bigots, who never have had thy love shed abroad in their hearts, can unfeelingly deal in the damnation of their fellows.
