2 Chronicles 20:21
And when he had consulted with the people, he appointed singers to the LORD, and that should praise the beauty of holiness…
When the Spartans marched into battle, they advanced with cheerful songs, willing to fight; but when the Persians entered the conflict, you could hear, as the regiments came on, the crack of the whip, by which the officers drove the cowards to the fray. What wonder that the Spartans were like lions in the midst of Sheep! Were we enthusiastic soldiers of the Cross, through God's help, nothing would be able to stand against us.
( C. H. Spurgeon.)
