This section appropriately follows x. 10, where the priests are enjoined to distinguish between the clean and the unclean. Laws concerning the animals which may or may not be eaten--quadrupeds, fish, birds, flying insects, creeping insects, reptiles--and pollution through contact with carcasses (xi.). Laws concerning the purification of women after childbirth (xii.). Laws for the detection of leprosy in the human body, xiii. 1-46, and in garments, xiii. 47-59. Laws for the purification of the leper and his re-adoption into the theocracy, xiv. 1-32. Laws concerning houses afflicted with leprosy, xiv. 33-57. Laws concerning purification after sexual secretions (xv.). The laws of purification are appropriately concluded by the law for the great day of atonement, with regulations for the ceremonial cleansing of the high priest and his house, the sanctuary, altar, and people (xvi.). Two originally independent sections appear to be blended in this chapter-one (cf. _vv._ 1-4) prescribing regulations to be observed by the high priest on every occasion on which he should enter the inner sanctuary, the other with specific reference to the great day of atonement. IV. LAW OF HOLINESS (xvii.-xxvi.) This section, though still moving largely among ritual interests, differs markedly from the rest of the book, partly by reason of its hortatory setting (cf. xxvi.), but especially by its emphasis on the ethical elements in religion. It has been designated the Law of Holiness because of the frequently recurring phrase, "Ye shall be holy, for I, Jehovah, am holy," xix. 2, xx. 26--a phrase which, though not peculiar to this section (cf. xi. 44), is highly characteristic of it. Animals are to be slaughtered for food or sacrifice only at the sanctuary xvii. 1-9; the blood and flesh of animals dying naturally or torn by beasts is not to be eaten, xvii. 10-16. Laws regulating marriage and chastity with threats of dire punishment for violation of the same (xviii.). Penalties for Moloch worship, soothsaying, cursing of parents and unchastity (xx.), with a hortatory conclusion, xx. 22-24, similar to xviii. 24-30. Ch. xix. is the most prophetic chapter in Leviticus, and bears a close analogy to the decalogue, _vv_. 3-8 corresponding to the first table, and _vv_. 11-18 to the second. The holiness which Jehovah demands has to express itself not only in reverence for Himself and His Sabbaths, but in reverence towards parents and the aged; in avoiding not only idolatry and heathen superstition, but dishonesty and unkindness to the weak. The ideal is a throroughly moral one. A modern reader is surprised to find in so ethical a chapter a prohibition of garments made of two kinds of stuff mingled together _v_. 19; no doubt such a prohibition is aimed at some heathen superstition--perhaps the practice of magic.
