Mat 8:5-13 MKJV
(5) And when Jesus had entered into Capernaum, a centurion came to him, beseeching Him,
(6) and saying, Lord, my son lies at home paralyzed and grievously tormented.
(7) And Jesus says to him, I will come and heal him.
(8) The centurion answered and said, Lord, I am not worthy that You should come under my roof; but only speak the word, and my boy will be healed.
(9) For I am a man under authority, having soldiers under me. And I say to this one, Go! And he goes; and to another, Come! And he comes; and to my servant, Do this! And he does it.
(10) When Jesus heard, He marvelled and said to those who followed, Truly I say to you, I have not found such great faith, no, not in Israel.
(11) And I say to you that many shall come from the east and the west, and shall sit down with Abraham and Isaac and Jacob in the kingdom of Heaven.
(12) But the sons of the kingdom shall be cast out into outer darkness; there shall be weeping and gnashing of teeth.
(13) And Jesus said to the centurion, Go. And as you have believed, so let it be to you. And his boy was healed in that hour.
