Bonaventure, on Song 4:4

“Thy neck, is as the tower of David, which is built with bulwarks: a thousand bucklers hang upon it, all the armour of valiant men.”

“"Thy neck is as the tower of David, which is built with bulwarks: a thousand bucklers hang upon it, all the armor of valiant men." This was said to the bride or mother Church, whose neck is like the tower of David. It is called the neck, whence the doctrine of truth goes forth. The neck serves us for two things, namely, for receiving food and for expressing words. Thus mother Church is called the neck, because from her the doctrine of truth goes forth: whence it says: "a thousand bucklers hang upon it." Likewise, from her proceeds the universality of words for strengthening souls: whence it says: "all the armor of valiant men." There is nothing that avails for having spiritual fortitude that sacred Scripture does not set forth.”
