Sufficiency of Scritpure

After these things Jesus went away to the other side of the Sea of Galilee (or Tiberias). A large crowd followed Him, because they saw the [a]signs which He was performing on those who were sick. Then Jesus went up on the mountain, and there He sat down with His disciples. Now the Passover, the feast of the Jews, was near. Therefore Jesus, lifting up His eyes and seeing that a large crowd was coming to Him, said to Philip, “Where are we to buy bread, so that these may eat?” This He was saying to test him, for He Himself knew what He was intending to do. Philip answered Him, “Two hundred denarii worth of bread is not sufficient for them, for everyone to receive a little.” One of His disciples, Andrew, Simon Peter’s brother, *said to Him, “There is a lad here who has five barley loaves and two fish, but what are these for so many people?” Jesus said, “Have the people sit down.” Now there was much grass in the place. So the men sat down, in number about five thousand. Jesus then took the loaves, and having given thanks, He distributed to those who were seated; likewise also of the fish as much as they wanted. When they were filled, He *said to His disciples, “Gather up the leftover fragments so that nothing will be lost.” So they gathered them up, and filled twelve baskets with fragments from the five barley loaves which were left over by those who had eaten. Therefore when the people saw the sign which He had performed, they said, “This is truly the Prophet who is to come into the world.”
