2 Chronicles 20:12 - Joseph Benson’s Commentary on the Old and New Testaments

O our God, wilt thou not judge them? He appeals to the justice of God, the righteous Judge, who rights those that suffer wrong, especially when they have no helper. Wilt thou not give sentence against them, and execute it upon them? For to judge, in this place, signifies to punish, as it also does in many other passages. The justice of God is the refuge of those that are wronged. We have no might against this great company It may seem strange that he should say they had no might, when he had so many hundred thousand men at command as are mentioned 2 Chronicles 17:14-16, &c. But it may be observed, that this was probably such a sudden invasion, that he had not time to gather any considerable body to oppose them; or rather, he distrusted the greatest army, and acknowledged it to be of no force if God were not with him, on whom he entirely relied, and not on the number and valour of his soldiers, though both were very great.
