OT Pseudepigrapha

2 Enoch 16:1

THOSE men showed me the other course, that of the moon, twelve great gates, crowned from west to east, by which the moon goes in and out of the customary times.

Ascension of Isaiah 11:17

And I saw: In Nazareth He sucked the breast as a babe and as is customary in order that He might not be recognized.

The Letter of Aristeas 7:4

The king was very anxious to meet the envoys, and gave orders that all the other officials should be dismissed and the envoys summoned to his presence at once. 5 Now this excited general surprise, for it is customary for those who come to seek an audience with the king on matters of importance to be admitted to his presence on the fifth day, while envoys from kings or very important cities with difficulty secure admission to the Court in thirty days--but these men he counted worthy of greater honour, since he held their master in such high esteem, and so he immediately dismissed those whose presence he regarded as superfluous and continued walking about until they came in and he was able to welcome them.

Ethiopian Orthodox Broader Canon

Testament of Our Lord, Book II 6:1

But if they are severally chosen to receivethe laver, let them be proved and investigated first, how they have lived while catechumens,’ if they have honoured widows, if they have visited the sick, if they have walked in all meekness and love,” if they were earnest in good works. But let them be borne witness to by those who bring them. And when they hear the Gospel, let a hand be laid on them daily. Let them be exorcised from that day when they are chosen. And let them be baptized in the days of Pascha. And when the days approach, let the bishop exorcise each one of them separately by himself, so that he may be persuaded that he is pure. For if there be one that is not pure, or in whom is an unclean spirit, let him be reproved by that unclean spirit. If then any one is found under any such imagination, let him be removed from the midst [of them], and let him be reproved and reproached that he hath not heard the word of the commandments and of instruction faithfully, because the evil and strange spirit abided in him. Let those who are about to receive the laver be taught on the fifth day of the last week only, to wash and bathetheir heads. But if any woman then be in the customary flux, let her also take in addition another day, washing and bathing beforehand. Let them fast both [on] the Friday and [on] the Saturday.
