The law of the sacrifice of the red cow, and the water of expiation.
[1] And the Lord spoke to Moses and Aaron, saying: [2] This is the observance of the victim, which the Lord hath ordained. Command the children of Israel, that they bring unto thee a red cow of full age, in which there is no blemish, and which hath not carried the yoke: [3] And you shall deliver her to Eleazar the priest, who shall bring her forth without the camp, and shall immolate her in the sight of all: [4] And dipping his finger in her blood, shall sprinkle it over against the door of the tabernacle seven times, [5] And shall burn her in the sight of all, delivering up to the fire her skin, and her flesh, and her blood, and her dung.
[2] “A red cow”: This red cow, offered in sacrifice for sin, and consumed with fire without the camp, with the ashes of which, mingled with water, the unclean were to be expiated and purified; was a figure of the passion of Christ, by whose precious blood applied to our souls in the holy sacraments, we are cleansed from our sins.
