In the feast-day,— At the festival,— εν τη εορτη. Dr. Heylin renders it at the festival of the passover. See on Matthew 26:5. The miracles here spoken of, as well as those Ch. John 3:2 and John 4:45 plainly refer to some miracles wrought by Christ, the particulars of which are not transmitted to us.
