Charles H. Spurgeon on Psalms 20:5

"In the name of our God we will set up our banners." 1. We will wage war in his name, we will see that our cause be good, and make his glory our end in every expedition; we will ask counsel at his mouth, and take him along with us; we will follow his conduct, implore his aid, and depend upon it, and refer the issue to him. David went against Goliath in the name of the Lord of hosts. 1 Samuel 17:45. 2. We will celebrate our victories in his name. When "we lift up our banners" in triumph, and set up our trophies, it shall be "in the name of our God," he shall have all the glory of our success, and no instrument shall have any part of the honour that is due to him. —Matthew Henry.
