Ex. xii. 9:  the head with the feet.  The same figurative interpretation is given by Eusebius (Eccl. Hist. I. ii. § 1):  “In Christ there is a twofold nature; and the one—in so far as He is thought of as God—resembles the head of the body, while the other may be compared with the feet,—in so far as He, for the sake of our salvation, put on human nature with the same passions as our own.”
