23 And the children of Ammon and Moab made an attack on the people of Mount Seir with a view to their complete destruction; and when they had put an end to the people of Seir, everyman's hand was turned against his neighbour for his destruction.

Matthew Henry's Commentary on 2 Chronicles 20:23

Commentary on 2 Chronicles 20:20-30

(Read 2 Chronicles 20:20-30)

Jehoshaphat exhorted his troops to firm faith in God. Faith inspires a man with true courage; nor will any thing help more to the establishing of the heart in shaking times, than a firm belief of the power, and mercy, and promise of God. In all our trust in the Lord, and our praises of him, let us especially look at his everlasting mercy to sinners through Jesus Christ. Never was an army so destroyed as that of the enemy. Thus God often makes wicked people destroy one another. And never was a victory celebrated with more solemn thanksgivings.
