The “arm” of Jehovah God is immeasurably powerful, able to do marvelous creative works. (Jer 27:5; 32:17) By his “arm” Jehovah also rules (Isa 40:10; Eze 20:33), saves those in distress (Ps 44:3; Isa 52:10), delivers his people (Ex 6:6; Isa 63:12; Ac 13:17), supports and cares for them (De 33:27; Isa 40:11; Ho 11:3), judges (Isa 51:5), and scatters his enemies (Ps 89:10; Lu 1:51).

Jehovah warns his people of the fallacy and disaster of trusting in the human arm. (2Ch 32:8; Jer 17:5) He will break the arm of the wicked, which is described as resting oppressively on their victims.​—Job 35:9; 38:15; Ps 10:15.
