H. Clay Trumbull, The Blood Covenant: A Primitive Rite and its Bearings on Scripture
“ All the world over, men who were in the covenant of blood-friendship were ready,—or were supposed to be ready,—to give not only their lives for each other, but even to give, for each other, that which was dearer to them than life itself. And, all the world over, men who pledged their devotedness to their gods were ready to surrender to their gods that which they held as dearest and most precious—even to the extent of their life, and of that which was dearer than life. Would Abraham do as much for his Divine Friend, as men would do for their human friends? ”
