C. F. Keil and Franz Delitzsch on Psalms 33:4-5

Psa 33:4-5

Now beings the body of the song. The summons to praise God is supported (1) by a setting forth of His praiseworthinessWe have adopted the word “praiseworthiness” for the sake of conciseness of expression, in order to avoid an awkward periphrasis, in the sense of being worthy to be praised. - Tr. (a) as the God of revelation in the kingdom of Grace. His word is ישׂר, upright in intention, and, without becoming in any way whatever untrue to itself, straightway fulfilling itself. His every act is an act in אמוּנה, truth, which verifies the truth of His word, and one which accomplishes itself. On אהב, equivalent to אהב הוּא, vid., Psa 7:10; Psa 22:29. צדקה is righteousness as conduct; משׁפּט is right as a rule of judgment and a state or condition. חסד is an accusative, as in Psa 119:64 : misericordia Domini plena est terra (the introit for Misercordias Sunday or the second Sunday after Easter).
