In those days, the apostles returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day's journey away; and when they had entered, they went up to the upper room, where they were staying, Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaios and Simon the Zealot and Judas the son of James. All these with one accord devoted themselves to prayer, together with the women and Mary the mother of Jesus, and with his brothers.

In those days Peter stood up among the brethren (the company of persons was in all about a hundred and twenty), and said, "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. For he was numbered among us, and was allotted his share in this ministry. "So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us, 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."

And they put forward two, Joseph called Barsabbas, who was surnamed Justos, and Matthias. And they prayed and said, "Lord, who knowest the hearts of all men, show which one of these two thou hast chosen to take the place in this ministry and apostleship from which Judas turned aside, to go to his own place." And they cast lots for them, and the lot fell on Matthias; and he was enrolled with the eleven apostles.

The Lord said to his disciples, "Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven. Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. For where two or three are gathered in my name, there am I in the midst of them."

Then Peter came up and said to him, "Lord, how often shall my brother sin against me, and I forgive him? As many as seven times?" Jesus said to him, "I do not say to you seven times, but seventy times seven."

Now when Jesus had finished these sayings, he went away from Galilee and entered the region of Judea beyond the Jordan; and large crowds followed him, and he healed them there.

Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people; but Jesus said, "Let the children come to me, and do not hinder them; for to such belongs the kingdom of heaven." And he laid his hands on them and went away.
