Obeying an angel, Cornelius sent men to summon Peter.

Acts 10:1-8

10 There was a man who lived in Caesarea city whose name was Cornelius. He was an officer who commanded 100 men in a large group of Roman soldiers from Italy. 2 He always tried to do what would please God; he and his entire household [MTY] were non-Jews who habitually worshipped God. He sometimes gave money to help poor Jewish people, and he prayed to God regularly.

3 One day at about three o’clock in the afternoon Cornelius saw a vision. He clearly saw an angel whom God had sent. The angel came into his room and said to him, “Cornelius!” 4 Cornelius stared at the angel and became terrified. Then he asked fearfully, “Sir, what do you (sg) want?” The angel answered him, “You (sg) have pleased God because you have been praying regularly to him and you often give money to help poor people. Those things have been like a sacrifice to God. 5 So, now command some men to go to Joppa and tell them to bring back a man named Simon whose other name is Peter. 6 He is staying with a man, also named Simon, who makes leather. His house is near the ocean.” 7 When the angel who spoke to Cornelius had gone, Cornelius summoned two of his household servants and a soldier who served him, one who also worshipped God. 8 He explained to them everything that the angel had said. Then he told them to go to Joppa to ask Peter to come to Caesarea.
