Here is one subtle illustration:
“When Robert Hall, the future great preacher, was a little boy, he heard the Rev. John Ryland, Baptist minister of Northampton, say to his father, ‘If I were Washington I would summon all the American officers, they should form a circle around me, and I would address them, and we would offer a libation in our own blood, and I would order one of them to bring me a lancet and a punch-bowl, and we would bare our arms and be bled, and when the bowl was full, when we all had been bled, I would call on every man to consecrate himself to the work by dipping his sword into the bowl, and entering into a solemn covenant engagement by oath, one to another, we would swear by him that sits upon the throne and liveth for ever and ever that we would never sheath our swords while there was an English soldier in arms remaining in America.’”
