During a time when Jesus was in the region of Galilee, large crowds of people gathered before him, bringing people who suffered from a variety of ailments, including being mute, invalid or blind. Jesus miraculously healed them. At one point, there was a large crowd of about 4000 men and their families who had nothing to eat. Jesus miraculously fed them. As explained in the Gospel of Matthew:
Jesus called his disciples to him and said, "I have compassion for these people; they have already been with me three days and have nothing to eat. I do not want to send them away hungry, or they may collapse on the way."
His disciples answered, "Where could we get enough bread in this remote place to feed such a crowd?"
"How many loaves do you have?" Jesus asked.
"Seven," they replied, "and a few small fish."
He told the crowd to sit down on the ground. Then he took the seven loaves and the fish, and when he had given thanks, he broke them and gave them to the disciples, and they in turn to the people. They all ate and were satisfied. Afterward the disciples picked up seven basketfuls of broken pieces that were left over. The number of those who ate was four thousand men, besides women and children. After Jesus had sent the crowd away, he got into the boat and went to the vicinity of Magadan.
- Matthew 15:29-39, NIV translation.
There is a separate miracle in which Jesus miraculously fed 5,000 families.
