The legislation of chapters xxviii.-xxx. appears to belong to a time of developed ritual and organised society. Parallel passages in Exodus and Leviticus treating of the feasts and offerings are by no means so full in their details, nor do they even mention some of the sacrifices here made statutory. The observances of New Moon are enjoined in the Book of Numbers alone. In chapter xv. they are simply noticed; here the order is fixed. The purpose of chapters xxviii., xxix. is especially to prescribe the number of animals that are to be offered throughout the year at a central altar, and the quantities of other oblations which are to accompany them. But the rotation of feasts is also given in a more connected way than elsewhere; we have, in fact, a legislative description of Israel's Sacred Year. Daily, weekly, monthly, and at the two great festal seasons, Jehovah is to be acknowledged by the people as the Redeemer of life, the Giver of wealth and blessedness. Of their cattle and sheep, and the produce of the land, they are to bring continual oblations, which are to be their memorial before Him. By their homage and by their gladness, by afflicting themselves and by praising God, they shall realise their calling as His people. The section regarding vows (ch. xxx.) completes the legislation on that subject, supplementing Lev. xxvii. and Numb. vi. It is especially interesting for the light it throws on the nature of family life, the position of women and the limitations of their freedom. The link between the law of offerings and the law of vows is hard to find; but we can easily understand the need for rules concerning women's vows. The peace of families might often be disturbed by lavish promises which a husband or a father might find it impossible or inconvenient to fulfil. 1. THE SACRED YEAR NUMBERS xxviii.-xxix Throughout the year, each day, each sabbath, and each month is to be consecrated by oblations of varying value, forming a routine of sacrifice. First the Day, bringing duty and privilege, is to have its morning burnt offering of a yearling lamb, by which the Divine blessing is invoked on the labour and life of the whole people. A meal offering of flour and oil and a drink offering of "strong drink"--that is, not of water or milk, but wine--are to accompany the sacrifice. Again in the evening, as a token of gratitude for the mercies of the day, similar oblations are to be presented. Of this offering the note is made: "It is a continual burnt offering, which was ordained in Sinai for a sweet savour, a sacrifice made by fire unto the Lord."
