Psalms 145:17

The Lord is righteous in all his ways - In his own character; in his laws; in his providential dealings; in his arrangements for the redemption and salvation of man. In his own character he is what it is desirable that a God should be; in all his laws he ordains that only which it is desirable should be enacted; in all his dealings with people he does that which it is desirable should be done. He violates no right; he wrongs no one; he demands of no one a service which would be unjust; he makes no arrangements for pardon and salvation which it is not best should be made. It is much for a man to be able to say in all that occurs to him under the divine administration, “It is right;” it is much for a man to have such confidence in God as to be able to feel that all he does in respect to nations is the best thing that could be done. Compare Psalms 89:14, note; Psalms 97:2, note.

And holy in all his works - Margin, merciful, or bountiful. The Hebrew word is merciful. The idea seems to be that righteousness and mercy are equally consulted in his arrangements; that they meet together, and act harmomoniously in the divine plans. Compare the notes at Psalms 85:10.
