Thy neck is like the tower of David builded for an armoury, whereon there hang a thousand bucklers, all shields of mighty men. Thy two breasts are liketwo young roesthat aretwins, which feed among the lilies.Until the day break, and the shadows flee away, I will get me to the mountain of myrrh, and tothehill of frankincense.Thou art all fair, my love; there is no spot in thee.
