First Reading: Acts 1:15-17, 20-26

¹⁵ In those days Peter stood up among the brethren (the company of persons was in all about a hundred and twenty), and said,
¹⁶ ”Brethren, the scripture had to be fulfilled, which the Holy Spirit spoke beforehand by the mouth of David, concerning Judas who was guide to those who arrested Jesus.
¹⁷ For he was numbered among us, and was allotted his share in this ministry.
²⁰ For it is written in the book of Psalms, `Let his habitation become desolate, and let there be no one to live in it’; and `His office let another take.’
²¹ So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us,
²² beginning from the baptism of John until the day when he was taken up from us — one of these men must become with us a witness to his resurrection.”
²³ And they put forward two, Joseph called Barsab’bas, who was surnamed Justus, and Matthi’as.
²⁴ And they prayed and said, “Lord, who knowest the hearts of all men, show which one of these two thou hast chosen
²⁵ to take the place in this ministry and apostleship from which Judas turned aside, to go to his own place.”
²⁶ And they cast lots for them, and the lot fell on Matthi’as; and he was enrolled with the eleven apostles.
