I will offer. — Such a holocaust could hardly have been vowed by a single person. It is the community that speaks. Besides, the ram was not a sacrifice for any individual, but particularly enjoined for the high priest (Leviticus 9:2), the head of a tribe (Numbers 7), or a Nazarite (Numbers 6:14). Incense is here the ascending smoke of the sacrifice.
