16 “‘And if the sacrifice of his offering is a vow+ or a voluntary offering,+ it is to be eaten on the day of his presenting his sacrifice, and on the next day what is left of it also may be eaten.

21 “‘And in case a man should present a communion sacrifice+ to Jehovah in order to pay a vow+ or as a voluntary offering, it should prove to be a sound one among the herd or the flock, in order to gain approval. No defect at all should prove to be in it.
