SEV Biblia, Chapter 20:21
Y habido consejo con el pueblo, puso a algunos que cantasen al SEŅOR, y alabasen en la hermosura de la santidad, mientras que salía la gente armada, y dijesen: Confesad al SEŅOR, porque su misericordia es para siempre.
John Gill's Bible Commentary
Ver. 21. And when he had consulted with the people , etc.] His principal officers, in what order they should march, and in what manner they should form themselves, when they met the enemy, and how they should conduct as if they were to engage: he appointed singers unto the Lord ; to sing his praise, and give him glory, as if the victory was already completed, it being so sure: and that should praise the beauty of holiness, as they went out before the army ; that is, praise God, who is glorious in holiness, whose beauty lies in his holiness, and who is holy in all his ways and works: and to say, praise the Lord, for his mercy endureth for ever ; with which they were to conclude their songs of praise, as David did, and whose songs they might sing; (see <19D601> Psalm 136:1-26).
Matthew Henry Commentary
Verses 20-30 - Jehoshaphat exhorted his troops to firm faith in God. Faith inspires man with true courage; nor will any thing help more to the establishin of the heart in shaking times, than a firm belief of the power, an mercy, and promise of God. In all our trust in the Lord, and ou 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. An never was a victory celebrated with more solemn thanksgivings.
