What does the imagery of the Lord making his arm bare relate to?

Thomas R. Valletta

“In ancient times, men prepared for battle by throwing their cloak away from the shoulder of their fighting arm (Ps. 74:11). At the second coming of Christ, God will make bare his arm when he shows forth his power for all to see (D&C 133:2–3)” (Parry et al., Understanding Isaiah, 466).
