These parts are consecrated in the name and stead of all the rest; the ear, as the instrument of hearing and receiving the mind and will of God in all their sacred administrations, and in their whole conversation; the hand and foot, as the instruments of action and execution of that which they hear and understand to be the mind of God; and the right parts are chosen rather than the left, as being usually more vigorous and expeditious. And all these parts are sprinkled with this blood, to show the absolute necessity of Christ's blood to qualify them for an acceptable and successful discharge of their office.
