The story of the woman with the issue of blood is a bit weird yet significant. She had been bleeding for 12 years and believed that just touching the hem of Jesus' garment would heal her. And it did. This shows the power of faith in Jesus, even a small amount of faith can bring about great miracles. It also shows Jesus' compassion for the outcasts of society, as this woman was considered unclean.
The story of the feeding of the 5000 is a bit of a mystery. Jesus took just a few loaves and fishes and multiplied them to feed a huge crowd. This not only shows Jesus' ability to perform miracles but also his concern for the physical well - being of the people. It can also be seen as a foreshadowing of the spiritual nourishment that Jesus would provide for all through his sacrifice.
