(Latin.) Place for repentance- that is, the licence of drawing back from a bargain, which can be done before any act has been committed to confirm it. In the interview between Esau and his father Isaac, St. Paul says that the former “found no place for repentance, though he sought it carefully with tears” (Heb. xii. 17) —i.e. no means whereby Isaac could break his bargain with Jacob.
