Incense & Arrows with Randy Martinez recorded “O Mighty Ones (Praise Is My Weapon)” as a short call to praise with a battle theme. It begins by quoting the psalms, “Bless the Lord, O mighty ones, bless the Lord, you heavenly hosts, bless the Lord, all you His angels,” and says the whole earth is his dominion. The singers then invite everyone nearby, “Come on and bless Him, come on and praise His name.”
They give the reason in a single line, “For the Lord delights in showing mercy.” The song then moves from heaven to the person singing it. “When I move my body, when I move my feet, when I open my mouth, then the darkness flees.” The last lines make the point of the title: “Worship is my warfare, my praise is a weapon.” The idea is that praise is an active choice that changes the atmosphere, not just a feeling. It is simple and chant-like, which makes it easy for a group to repeat.
The call to the angels and hosts is Psalm 103:20-22. God delighting to show mercy is Micah 7:18, and singers going ahead of an army is 2 Chronicles 20:21-22.
