 The husband was required to make a sacrifice to God, as part of the ritual, probably due to a general principle that no one should seek answers from God without giving something in return.This offering is required to be placed in the wife's hands, and is literally described as "her offering for her"; scholars think that it is the man's offering, in relation to the ordeal of his wife, and that her holding of it is merely symbolic of this.The offering specified is one tenth of an ephah of barley meal, unaccompanied by oil or frankincense; this is the cheaper type of flour, unlike the flour specified for all other biblical sacrifices.
