Charles H. Spurgeon on Psalms 20:5

"In the name of our God." As those cried out, Judges 7:20, "The sword of the Lord and of Gideon;" and as we have it in Joshua 6:20, "And the people shouted, and the walls of Jericho fell down;" and king Abiah, crying out with his men in the same, killed five hundred thousand of the children of Israel; and so now also, according to the military custom in our day, the soldiers boast in the name and glory of their general, in order to encourage themselves against their enemies. And it is just this custom that the present verse is now teaching, only in a godly and religious manner. —Martin Luther.
