15.48

若比丘囑授欲詣村，而中道還，失前囑授；後若欲去者當更囑授。若比丘囑授欲詣村，不至所囑授處，乃更詣餘家，失前囑授；若欲往，應更囑授而去。若囑授至白衣家，乃更至庫藏處及聚落邊房，若至比丘尼僧伽藍中，若即白衣家還出，失前囑授；應更囑授而往。

If a bhikṣu gives notification wishing to go to a village, but turns back midway, he forfeits the previous notification; if he later wishes to go, he must give notification again. If a bhikṣu gives notification wishing to go to a village, but does not go to the place notified, going instead to another family, he forfeits the previous notification; if he wishes to go, he must give notification again and then go. If he gives notification that he is going to a layperson's house, but goes instead to a storehouse, or to a dwelling on the edge of a village, or to a bhikṣuṇī monastery, or goes to the layperson's house and immediately leaves, he forfeits the previous notification; he must give notification again and then go.
