He shall bring them to the priest, who shall offer first that which is for the sin offering and shall nip its head at the front of its neck, but he shall not sever it.

Then he presented the people’s offering, and took the goat of the sin offering which was for the people, and slaughtered it and offered it for sin, like the first.
