Acts 1:12-14 Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day’s journey away; 13 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 Alphaeus and Simon the Zealot and Judas the son of James. 14 All these with one accord devoted themselves to prayer, together with the women and Mary the mother of Jesus, and with his brethren.
Acts 1:16-18
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.
Acts 2:14-18 14 But Peter, standing with the eleven, lifted up his voice and addressed them, “Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. 15 For these men are not drunk, as you suppose, since it is only the third hour of the day; 16 but this is what was spoken by the prophet Joel:

Acts 15:6-14
6 The apostles and the elders were gathered together to consider this matter. 7 And after there had been much debate, Peter rose and said to them, “Brethren, you know that in the early days God made choice among you, that by my mouth the Gentiles should hear the word of the gospel and believe. 8 And God who knows the heart bore witness to them, giving them the Holy Spirit just as he did to us; 9 and he made no distinction between us and them, but cleansed their hearts by faith. 10 Now therefore why do you make trial of God by putting a yoke upon the neck of the disciples which neither our fathers nor we have been able to bear? 11 But we believe that we shall be saved through the grace of the Lord Jesus, just as they will.”
12 And all the assembly kept silence; and they listened to Barnabas and Paul as they related what signs and wonders God had done through them among the Gentiles. 13 After they finished speaking, James replied, “Brethren, listen to me. 14 Symeon has related how God first visited the Gentiles, to take out of them a people for his name.
