8 But ye shall offer a burnt offering unto the LORD for a sweet savour; one young bullock, one ram, and seven lambs of the first year; they shall be unto you without blemish:
9 And their meat offering shall be of flour mingled with oil, three tenth deals to a bullock, and two tenth deals to one ram,
10 A several tenth deal for one lamb, throughout the seven lambs:
11 One kid of the goats for a sin offering; beside the sin offering of atonement, and the continual burnt offering, and the meat offering of it, and their drink offerings.
