Numbers 19:2

2“This is the ritual that the Lord has appointed for a victim. Instruct the sons of Israel, so that they may bring to you a red cow of full maturity, in which there is no blemish, and which has not carried a yoke.
19:2 A red cow, etc: 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.(Challoner)
