Psalms 103:20-22 - Joseph Benson’s Commentary on the Old and New Testaments

Bless the Lord, ye his angels Who, though glorious creatures, are but his ministers and messengers, as the word signifies. And by inviting the angels to bless God he excites men to the same duty, as having more dependance upon God, and obligation to him. That excel in strength Of which see one evidence, 2 Kings 19:35. You are freed from the inabilities and infirmities of mankind; that do his commandments That live in a universal, constant, and perfect obedience to all God's commands; hearkening unto the voice of his word Who diligently wait for his commands, and execute them with all cheerfulness and readiness. Bless the Lord, all ye his hosts The angels again, to whom he still continues his address, and whom he more particularly describes by the name of hosts, a title often given to them on account of their vast numbers, mighty power, unanimous concurrence, and exquisite order. Ye ministers of his The Hebrew word משׁרתיו, mesharethaiv, thus rendered, is commonly used of the highest and most honourable sort of servants; that do his pleasure Whose constant business and delight it is to execute his orders and fulfil his will. Bless the Lord, all his works, in all places of his dominion All creatures, both in heaven and earth, according to your several capacities. Bless the Lord, O my soul Which thou hast especial and abundant reason to do. Thus he ends the Psalm with the same words wherewith he began it.
