The apostles and other believers often prayed together.

Acts 1:12-14

12 Then after the two angels left, the apostles returned to Jerusalem from Olive Tree Hill, which was about ◄a half mile/one kilometer► [MTY] from Jerusalem. 13 When they entered the city, they went upstairs to the room in the house where they were staying. Those who were there included Peter, John, James, Andrew, Philip, Thomas, Bartholomew, Matthew, another James the son of Alphaeus, Simon who belonged to the group that wanted to expel the Romans, and Judas the son of another man named James. 14 All these apostles agreed concerning the things about which they continually were praying together. Others who prayed with them included the women who had accompanied Jesus, Mary who was Jesus’ mother, and his younger brothers.
