At weekly circle of Samuel L. Sprague: "Br. P[hineai]. Richards [a member of Council of Fifty] spoke of coming in contact with our enemies. We have covenanted to avenge the blood of the Prophets and Saints. Why, then, should we hesitate to go forth and slay them-shed their blood-when called upon. Pres. Sprague spoke a few words in answer to the inquiry made by br. Richards; that the Lord had said 'vengeance is mine.' Nevertheless, we shall have blood to shed."
