And on the eighth day. — Though restored to social intercourse with his fellow brethren, the recovered leper could not at once be admitted to the privileges of the sanctuary, but had to bring on the eighth day three kinds of sacrifices: viz., a trespass offering, a sin offering, and a burnt offering. The lamb for the sin offering had not only to be without blemish (see Leviticus 1:3), but of the first year (see Leviticus 12:6).
And three tenth deals of fine flour. — Each of these three sacrifices is to be accompanied by a meat offering, consisting of a tenth part of an ephah (which is an omer) of flour. The omer, which is the same as “the tenth deal” (see Exodus 16:36), as it is here called, is equal to 43⅕ eggs, or about four pints. Ordinarily a meat offering did not accompany the trespass offering or the sin offering, and only one omer was brought with a lamb (see Numbers 15:4); but according to the administrators of the law during the second Temple, three omers are here prescribed as a substitute for the drink offering which should have accompanied the two expiatory sacrifices. For the manner in which the meat offering was prepared, see Leviticus 11:1-4.
And one log of oil. — This oil, as we see afterwards (see Leviticus 14:15, &c.), was used to sprinkle seven times before the Lord, to sanctify the ear, the hand, the foot, and the head of the restored leper. The measure log, which occurs four times in this section (Leviticus 14:10; Leviticus 14:12; Leviticus 14:15; Leviticus 14:21), is not to be found in any other part of the Hebrew Scriptures. According to the authorities at the time of Christ, a “log” is equal to six hen’s eggs.
