" CHAP. LXVII.—WEEKLY WORSHIP OF THE CHRISTIANS. And we afterwards continually remind each other of these things. And the wealthy among us help the needy; and we always keep together; and for all things wherewith we are supplied, we bless the Maker of all through His Son Jesus Christ, and through the Holy Ghost. And on the day called Sunday,[145] all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability,[146] and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given,[147] and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows, and those who, through sickness or any other cause, are in want, and those who are in bonds, and the strangers sojourning among us, and in a word takes care of all who are in need. But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, having wrought a change in the darkness and matter, made the world; and Jesus Christ our Saviour on the same day rose from the dead.

" When the people waged war with Amalek, and the son of Nave (Nun) by name Jesus (Joshua), led the fight, Moses himself prayed to God, stretching out both hands, and Hur with Aaron supported them during the whole day, so that they might not hang down when he got wearied. For if he gave up any part of this sign, which was an imitation of the cross, the people were beaten, as is recorded in the writings of Moses; but if he remained in this form, Amalek was proportionally defeated, and he who prevailed prevailed by the cross. For it was not because Moses so prayed that the people were stronger, but because, while one who bore the name of Jesus (Joshua) was in the forefront of the battle, he himself made the sign of the cross.
