Mark 5 is a chapter in the Bible. The Bible is a big book with lots of stories and teachings about God and Jesus. Mark 5 specifically tells us about some things that happened when Jesus was alive on earth.
In this chapter, we learn about how Jesus healed a man who was possessed by many evil spirits, how he brought a little girl back to life after she died, and how he healed a woman who had been sick for a really long time.
When we say someone is possessed by evil spirits, it means that they are being controlled by something bad and scary. Jesus was able to help the man and get rid of the evil spirits so that he could be healthy again.
When someone dies, it means that their body stops working and they can't breathe or move anymore. But Jesus had the power to bring the little girl back to life and make her alive again.
Finally, when we are sick, it means that our bodies don't feel good and we might have things like a fever, cough, or aches. Jesus was able to heal the woman who had been sick for a long time so that she could feel better.
Overall, Mark 5 is a chapter in the Bible that tells us about some amazing things that Jesus did to help people when he was alive.
