Psalms 103:21

All ye his hosts; ye ministers of his - We know almost nothing of the economy of the heavenly host; and, therefore, cannot tell what is the difference between angels, mighty powers, hosts, and ministers who do his pleasure. All owe their being and all its blessings to God; all depend upon his bounty; and without him they can do nothing; therefore, all should praise him.

Bless ye the Lord, all ye his hosts - His armies; the vast multitudes of holy beings, arranged and marshalled as hosts for battle, in all parts of the universe. Compare the notes at Isaiah 1:9; notes at Ephesians 1:21.

Ye ministers of his - The same beings referred to by the word "hosts," and all others who may be employed in executing his will. The "hosts" or armies of the Lord are thus marshalled that they may "do his pleasure," or that they may execute his purposes.

That do his pleasure - What is agreeable to him; that is, who perform his will. Employed in his service, and appointed to execute his will, they are called on to bless his name. The fact of being employed in his service is a sufficient reason for praise. It is implied here that those "ministers of his" actually do his will. They are obedient to his commands; they regard themselves as employed for him.

103:21 His hosts - A title often given to the angels, in regard of their vast numbers, mighty power, unanimous concurrence, and exquisite order. Ministers - This Hebrew word is commonly used of the highest and most honourable sort of servants,
