Matthew Poole and continuators on Psalms 103:21

21 Bless ye the LORD, all ye his hosts , ye ministers of his that do his pleasure .

Ye Angels; to whom he still continues his address, and whom he more particularly describes by the name of hosts, a title oft given to the Angels, as Gen. 32. 2. 1 Kings 22. 19. 2 Chron. 18. 18. Luk▪ 2. 13. Revel. 19. 14. in regard of their vast numbers, mighty power, unanimous concurrence, and exquisite order. In the former Verse the expression was indefinite definite and general, ye his angels, here it is universal and yet particular, all ye his hosts. He seems to apply himself to the several Orders of Angels, of whom see Eph. 3. 10. Coloss. 1. 16. and to each individual Angel.

This Hebrew word is commonly used of the highest and most honourable sort of Servants.

Whose constant business and delight it is to execute the will and commands of God.
