四分律比丘含注戒本 2.193

2.193

若於說戒時，座上問答已，若僧差，若隨尼請，彼比丘剋時到，尼亦剋時迎；若違，俱犯吉羅。若聞來者，當出半由旬迎，供給所須，不者吉羅。若僧不差，非教授日，與說八不違法，吉羅；若不差，與說法者，墮。若僧病、不和合、眾不滿，應遣人禮拜問訊；尼眾病等，亦遣禮拜問訊——若不，吉羅。比丘尼等二眾吉羅。不犯者，比丘尼眾如上方便已，而為水陸道斷諸難不容禮拜問訊者，並開。

(If at the time of reciting the precepts, questions and answers are finished on the seat, and if appointed by the Saṃgha, or following the bhikṣuṇīs' request, that bhikṣu arrives at the appointed time, and the bhikṣuṇīs also welcome him at the appointed time; if they fail to do so, both commit a duṣkṛta. If hearing that he is coming, they should go out half a yojana to welcome him and provide what is needed; if not, it is a duṣkṛta. If the Saṃgha has not appointed him, and on a non-instruction day he explains the eight non-transgressible dharmas to them, it is a duṣkṛta; if he is not appointed and preaches the Dharma to them, it is a prāyaścittika. If the Saṃgha is sick, not in concord, or incomplete, they should send someone to pay homage and inquire after them; if the community of bhikṣuṇīs is sick, etc., they should also send someone to pay homage and inquire—if not, it is a duṣkṛta. For the two groups of bhikṣuṇīs, etc., it is a duṣkṛta. Regarding non-offense: if the community of bhikṣuṇīs has made preparations as above, but because water or land routes are cut off or due to various perils they cannot pay homage and inquire, all are permitted.)
