God, however, graciously met his faith when greatly tried, as we find in the 20th chapter, where the Moabites and Ammonites and others came; and a beautiful instance of the piety of faith is shown us here in this way - for I shall only mention one single feature in this mere sketch of these chapters. It is that in going forth they went singing the song of victory. It was not like the Greek who raised his paean to frighten the enemy; but here it was the piety that ventured and counted upon the Lord. How blessed is faith, in the people of God! The consequence need scarcely be told. "The children of Ammon and Moab stood up against the inhabitants of mount Seir, utterly to slay and destroy [them]; and when they had made an end of the inhabitants of Seir, every one helped to destroy another." So when the men of Judah came, there was nothing to do but to reap the fruits. And well might they call it the valley of Berachah - the valley of praise. "For there they blessed Jehovah: therefore the name of the same place was called the valley of Berachah unto this day."
So then ends the course of Jehoshaphat with one solitary tale more; namely, the attempt to join with "Ahaziah, king of Israel, who did very wickedly. And he joined himself with him to make ships to go to Tarshish: And they made the ships in Ezion-gaber. Then Eliezer the son of Dodavah of Mareshah prophesied against Jehoshaphat, saying, Because thou hast joined thyself with Ahaziah, Jehovah hath broken thy works. And the ships were broken, and they were not able to go to Tarshish (2Ch_20:35-37).
What a contrast with Jehoshaphat's going forth and the victory made ready to his hand by the Lord God. And this is all instructive to us. May the Lord keep us true to His name and glory!
