How to explain the poem in Psalm 103:2 1

Psalm 103 2 1 "Praise the Lord, all of you who do what pleases him, his army and his servants. 」

"Be his master, his servant, and do what he likes. Praise god! 」

[tentative note] "army" is also called "the army in the sky", which refers to angels and is a servant sent by God.

The army. See poem 24:10; Luke 2: 13.

Servant. Corresponding to the "army" (see poem104: 4; But 7:10; Come 1: 14).
