The calendar of P comprises (a) the Feast of Passover and the Unleavened Cakes, vv. 4-8; (b) a fragment of Pentecost, v. 21; (c) the Feast of Trumpets, vv. 23-25; (d) the Day of Atonement, vv. 26-32; and (e) the Feast of Tabernacles, vv. 33-36, with a subscription in vv. 37, 38. With these have been incorporated the older regulations of H on the Feast of Weeks, or Pentecost, vv. 9-20, which have been retained in place of P's account (cf. v. 21), and on the Feast of Tabernacles, vv. 39-44, the latter being clearly intended to supplement vv. 33-36. The hand of the redactor who combined the two elements may be seen partly in additions designed to accommodate the regulations of H to P (e.g. v. 39a, "on the fifteenth day of the seventh month," and 39b, "and on the eighth day shall be a solemn rest"), partly in the later expansions corresponding to later usage, vv. 12 f., 18, 19a, 21b, 41. Further, vv. 26-32 (on the Day of Atonement, cf. xvi.) are a later addition to the P sections.
Chap. xxiv. affords an interesting illustration of the manner in which the redactor of P has added later elements to the original code of H. For the first part of the chapter, with its regulations as to (a) the lamps in the Tabernacle, vv. 1-4, and (b) the Shewbread, vv. 5-9, is admittedly derived from P, vv. 1-4, forming a supplement to Exod. xxv. 31-40 (cf. xxvii. 20 f.) and Num. viii. 1-4, and vv. 5-9 to Exod. xxv. 30. The rest of the chapter contains old laws (vv. 15b-22) derived from H on blasphemy, manslaughter and injuries to the person, to which the redactor has added an historical setting (vv. 10-14, 23) as well as a few glosses.
Chap. xxv. lays down regulations for the observance of (a) the Sabbatical year, vv. 1-7, 19-22, and (b) the year of Jubilees, vv. 8-18, 23, and then applies the principle of redemption to (1) land and house property, vv. 24-34, and (2) persons, vv. 35-55. The rules for the Sabbatical year (vv. 1-7) are admittedly derived from H, and vv. 19-22 are also from the same source. Their present position after vv. 8-18 is due to the redactor who wished to apply the same rules to the year of Jubilee. But though the former of the two sections on the year of Jubilee (vv. 8-18, 23) exhibits undoubted signs of P, the traces of H are also sufficiently marked to warrant the conclusion that the latter code included laws relating to the year of Jubilee, and that these have been modified by R_{ P} and then connected with the regulations for the Sabbatical year. Signs of the redactor's handiwork may be seen in vv. 9, 11-13 (the year of Jubilee treated as a fallow year) and 15, 16 (cf. the repetition of "ye shall not wrong one another," vv. 14 and 17). Both on historical and on critical grounds, however, it is improbable that the principle of restitution underlying the regulations for the year of Jubilee was originally extended to _persons_ in the earlier code. For it is difficult to harmonize the laws as to the release of Hebrew slaves with the other legislation on the same subject (Exod. xxi. 2-6; Deut. xv.), while both the secondary position which they occupy in this chapter and their more elaborate and formal character point to a later origin for vv. 35-55. Hence these verses in the main must be assigned to R_{ P}. In this connexion it is noticeable that vv. 35-38, 39-40a, 43, 47, 53, 55, which show the characteristic marks of H, bear no special relation to the year of Jubilee, but merely inculcate a more humane treatment of those Israelites who are compelled by circumstances to sell themselves either to their brethren or to strangers. It is probable, therefore, that they form no part of the original legislation of the year of Jubilee, but were incorporated at a later period. The present form of vv. 24-34 is largely due to R_{ P}, who has certainly added vv. 32-34 (cities of the Levites) and probably vv. 29-31.
