Psalms 103:21 - Exposition

Bless ye the Lord, all ye his hosts. Here the inferior angels seem to be meant—that "multitude of the host of heaven" which appeared to the shepherds on Christ's natal day ( Luke 2:13 ), and which is elsewhere often referred to in Holy Scripture. Ye ministers of his (comp. Psalms 104:4 ) that do his pleasure. The inferior, no less than the superior, ranks of angels continually carry out the will of God, being "ministering spirits, sent forth to minister for them who shall be heirs of salvation" ( Hebrews 1:14 ).
