And the following day they entered Caesarea. Now Cornelius was waiting for them, and had called together his relatives and close friends. 25 As Peter was coming in, Cornelius met him and fell down at his feet and worshiped him. 26 But Peter lifted him up, saying, “Stand up; I myself am also a man.” 27 And as he talked with him, he went in and found many who had come together. 28 Then he said to them, “You know how unlawful it is for a Jewish man to keep company with or go to one of another nation. But God has shown me that I should not call any man common or unclean. 29 Therefore I came without objection as soon as I was sent for. I ask, then, for what reason have you sent for me?”
30 So Cornelius said, “Four days ago I was fasting until this hour; and at the ninth hour I prayed in my house, and behold, a man stood before me in bright clothing, 31 and said, ‘Cornelius, your prayer has been heard, and your alms are remembered in the sight of God. 32 Send therefore to Joppa and call Simon here, whose surname is Peter. He is lodging in the house of Simon, a tanner, by the sea. When he comes, he will speak to you.’ 33 So I sent to you immediately, and you have done well to come. Now therefore, we are all present before God, to hear all the things commanded you by God.” — Acts 10:24-33.
Cornelius relates the incident of how four days ago he was fasting and praying. A man dressed in bright clothing, stands before him, and says that his prayer has been heard, and his alms remembered in the sight of God. He is instructed to send for Peter from Joppa who would speak to him. And so he sent for Peter immediately. Now they are all present before God, ready to hear all the things God has commanded Peter to say.
