To signify the accomplishment of the days of purification... — The process lasted, as the next verse shows, for seven days, which were probably reckoned from the completion of the thirty days, or other term, of the vow itself. St. Paul, having made himself the representative of the Nazarite company, had to give, in their name, the formal notice to the priests, who were to be ready for the sacrifices when the seven days had expired. Seven days was, it will be noted, the ordinary period for the more solemn purifications (Exodus 29:37; Leviticus 12:2; Leviticus 13:6; Numbers 12:14; Numbers 19:14, et al.).
