The abomination - i. e. an animal which the Egyptians held it sacrilegious to slay. The ox, bull, or cow, is meant. The cow was never sacrificed in Egypt, being sacred to Isis, and from a very early age the ox was worshipped throughout Egypt, and more especially at Heliopolis and Memphis under various designations, Apis, Mnevis, Amen-Ehe, as the symbol or manifestation of their greatest deities, Osiris, Atum, Ptah, and Isis.
