Sin-offering
   (Heb. hattath), the law of, is given in detail in Lev. 4-6:13;
   9:7-11, 22-24; 12:6-8; 15:2, 14, 25-30; 14:19, 31; Num. 6:10-14.
   On the day of Atonement it was made with special solemnity (Lev.
   16:5, 11, 15). The blood was then carried into the holy of
   holies and sprinkled on the mercy-seat. Sin-offerings were also
   presented at the five annual festivals (Num. 28, 29), and on the
   occasion of the consecration of the priests (Ex. 29:10-14, 36).
   As each individual, even the most private member of the
   congregation, as well as the congregation at large, and the high
   priest, was obliged, on being convicted by his conscience of any
   particular sin, to come with a sin-offering, we see thus
   impressively disclosed the need in which every sinner stands of
   the salvation of Christ, and the necessity of making application
   to it as often as the guilt of sin renews itself upon his
   conscience. This resort of faith to the perfect sacrifice of
   Christ is the one way that lies open for the sinner's attainment
   of pardon and restoration to peace. And then in the sacrifice
   itself there is the reality of that incomparable worth and
   preciousness which were so significantly represented in the
   sin-offering by the sacredness of its blood and the hallowed
   destination of its flesh. With reference to this the blood of
   Christ is called emphatically "the precious blood," and the
   blood that "cleanseth from all sin" (1 John 1:7).
