Acts of Apostles (Redactions AB)

First of all, I make this word concerning all of it, O God-loving one, which Jesus began in deed and teaching, until the day of his ascension he commanded the apostles by the Holy Spirit, whom he had chosen, and he ascended, to whom he presented his living self after his passion in many forms; for forty days he appeared to them and spoke to them concerning the kingdom of God, he conversed with them and commanded: "Do not depart from Jerusalem, but await that promise of the Father which you heard from me. For John gave baptism by water, but you shall receive baptism by the Holy Spirit not many days after these." And those who were gathered questioned him and said: "Lord, if at this time will the kingdom be restored to Israel?" And he himself said to them: "It is not yours to know the times or the years which the Father has set by his own authority; but bring forth power for the coming of the Holy Spirit upon you, and be my witnesses in Jerusalem and in all Judea and Samaria and unto the ends of the earth." And as he said this, while they were still looking, he ascended and a cloud received him from their sight.

And while they were still standing and looking at his ascension into heaven, behold, two men in white garments stood before them and said to them: "Men of Galilee, why do you stand and gaze heavenward? This Jesus, who ascended from you into heaven, will come again just as you have seen him ascending into heaven." Then they turned back from that mountain, which is called the Mount of Olives, which is near Jerusalem, about a Sabbath day's journey away. And when they entered the city, they went up to the upper room where Peter and John, James and Andrew, Philip and Thomas, Bartholomew and Matthew, James Alphaeus and Simon the Zealot, and Judas of James were staying. All these were gathered together in prayer with the women, and Mary, the mother of Jesus, and with his brothers. And in those days Peter stood up among the disciples and said (the whole company together numbered about one hundred and twenty men): "Men, it was necessary to fulfill this scripture, which the Holy Spirit foretold through the mouth of David concerning Judas, who became the leader of those who seized Jesus, for he was counted among us, and the portion of this service and apostleship was allotted to him; he acquired that field with the price of falsehood, and he burst open and scattered among them, and all his entrails were dispersed.

and it became known before all the inhabitants of Jerusalem that the valley called by them in their own speech Akeldama, that is the valley of blood. For it is written in the book of Psalms: "Let his dwelling place be desolate and let no one dwell therein; and let another take his inheritance." It is fitting for these men gathered with us at all times, among whom the Lord Jesus entered and departed from us, beginning from the baptism of John until the day of his ascension from us, to bear witness to his resurrection by being with us, one of these." And they appointed two: Joseph, who was called Barsabbas and later was named Justus, and Matthias. And they prayed and said: "You, Lord, knower of all hearts, reveal from these two the one to receive the lot of service, from which Judas departed to go to his own place." And they cast lots for them. And the lot fell upon Matthias, and he was counted as the twelfth among the eleven apostles.
