Leviticus 1:10-11

10, 11. Offering… of the flocks The burnt offering of a sheep or goat differed from that of the herd in these particulars: The sheep was to be killed on the side of the altar northward, for reasons not assigned: the impressive ceremony of laying the hand upon the head of the victim is absent; and also the declaration that it shall be accepted for an atonement. Hence we infer that either this offering, as well as that which follows, was not expiatory, or that the peculiar nature of the burnt offering was well understood. See Concluding Note, (1.)
