(7.) Deborah's own soul fought against them; she speaks of it with a holy exultation (v. 21): O, my soul, thou hast trodden down strength. She did it by exciting others to do it, and assisting them, which she did with all her heart. Also by her prayers; as Moses conquered Amalek by lifting up his hand, so Deborah vanquished Sisera by lifting up her heart. And when the soul is employed in holy exercises, and heart-work is made of them, through the grace of God the strength of our spiritual enemies will be trodden down and will fall before us.
