20 And they rise early in the morning, and go out to the wilderness of Tekoa, and in their going out Jehoshaphat hath stood and saith, 'Hear me, O Judah, and inhabitants of Jerusalem, remain stedfast in Jehovah your God, and be stedfast; remain stedfast in His prophets, and prosper.' 21 And he taketh counsel with the people, and appointeth singers to Jehovah, and those giving praise to the honour of holiness, in the going out before the armed 'men', and saying, 'Give ye thanks to Jehovah, for to the age 'is' His kindness.' 22 And at the time they have begun with singing and praise, Jehovah hath put ambushments against the sons of Ammon, Moab, and mount Seir, who are coming in to Judah, and they are smitten, 23 and the sons of Ammon stand up, and Moab, against the inhabitants of mount Seir, to devote and to destroy, and at their finishing with the inhabitants of Seir, they helped, a man against his neighbour, to destroy. 24 And Judah hath come in unto the watch-tower, to the wilderness, and they look unto the multitude, and lo, they 'are' carcases fallen to the earth, and there is none escaped, 25 and Jehoshaphat cometh in, and his people, to seize their spoil, and they find among them, in abundance, both goods and carcases, and desirable vessels, and they take spoil to themselves without prohibition, and they are three days seizing the spoil, for it 'is' abundant. 26 And on the fourth day they have been assembled at the valley of Blessing, for there they blessed Jehovah: therefore they have called the name of that place, 'Valley of Blessing,' unto this day. 27 And they turn back, every man of Judah and Jerusalem, and Jehoshaphat at their head, to go back unto Jerusalem with joy, for Jehovah hath made them rejoice over their enemies. 28 And they come in to Jerusalem with psalteries, and with harps, and with trumpets, unto the house of Jehovah. 29 And there is a fear of God on all kingdoms of the lands in their hearing that Jehovah hath fought with the enemies of Israel, 30 and the kingdom of Jehoshaphat is quiet, and his God giveth rest to him round about.

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.
