Goat
Goats, as in Leviticus 16:21, 22, signify faith. Because man is regenerated by the Lord by the truth of faith, and consequently, his sins are removed and cast into hell, therefore it is said that "Aaron made the goat bear upon him all the iniquities of the children of Israel unto the land of separation, or into the wilderness." From correspondences, a goat signifies the natural man. The goat which was sacrificed, as in Leviticus 16:5-10, signifies the natural man regarding a part purified, and the goat which was sent into the wilderness regarding the natural man not purified.

12
For I will go through the land of Egypt in that night, and will strike all the firstborn in the land of Egypt, both man and animal. Against all the gods of Egypt I will execute judgments: I am Yahweh.
13
The blood shall be to you for a token on the houses where you are: and when I see the blood, I will pass over you, and there shall no plague be on you to destroy you, when I strike the land of Egypt.
