He shall lay his hand upon the head of his offering— "This laying on of hands," says Conradus, "signifies devotion and faith, with acknowledgment of the Divine benefits, for which we can offer nothing of our own, but only return to God what we have received; so that we may understand gratitude and thanksgiving to be the most valuable of sacrifices;" see ch. Leviticus 1:4. It is well known, how great an abomination the sacrifice of a cow, the symbol of Isis, was held in Egypt; and, consequently, this permission of offering a male or female from the herd, shews a manifest opposition to the religious rites, of the Egyptians.
