Charles H. Spurgeon on Psalms 20:5

"Our banners." Will you know the staff, the colours, and the flag or streamer of this ensign? Why, the staff is his cross, the colours are blood and water, and the streamer the gospel, or preaching of them to the world. The staff that carried the colours, was of old time fashioned like a cross, a cross bar near the top there was, from which the flag or streamer hung; so as it were prefiguring, that all the hosts and armies of the nations were one day to be gathered under the banner of the cross, to which soldiers should daily flow out of all the nations and kingdoms of the earth. —Mark Frank, 1613-1664.
