And thou shalt speak unto the children of Israel, saying, Whosoever curseth his God shall bear his sin. Leviticus 23 and the first section of Leviticus 24 are concerned with corporate religious feasts. The second half of Leviticus 24 deals with blasphemy. The first section deals with covenant renewal through participation in corporate covenant-renewal celebrations. The second section deals with individual covenant-breaking by oath.
Covenant is an inescapable concept.
A man must affirm a covenant of some kind. He is, in Meredith G. Kline's words, by oath consigned. Covenantal affirmations in the modern world are usually implicit rather than explicit. Civil covenants are not normally established by explicit public oath except for political office-holders and members of the military. Marriage is today regarded as a contract rather than an oath-bound institution under God's sanctions in history.
