“And now send men to Joppa, and call for one Simon, whose surname is Peter:”
King James Version (KJV)
10:3 He saw in a vision - Not in a trance, like Peter: plainly, so as to leave one not accustomed to things of this kind no room to suspect any imposition.
10:4 Thy prayers and thine alms are come up for a memorial before God - Dare any man say, These were only splendid sins? Or that they were an abomination before God? And yet it is certain, in the Christian sense Cornelius was then an unbeliever. He had not then faith in Christ. So certain it is, that every one who seeks faith in Christ, should seek it in prayer, and doing good to all men: though in strictness what is not exactly according to the Divine rule must stand in need of Divine favour and indulgence.
Ac 10:5 Send men to Joppa. He is not told to go, because a soldier could not leave his post without orders, but to send. Joppa is about thirty miles south of Caesarea.
