AS A TESTIMONY TO THEM
Matthew 8:4 “Jesus said to him, “See that you don’t tell anyone. But go, show yourself to the priest and offer the gift Moses commanded, as a testimony to them.”
Jesus commanded this man not to tell anyone of his healing but still the man was told to go to the priest and offer a gift as a testimony.
The man wasn’t supposed to tell people at that time, but he still had to give testimony to the priest.
This means he had to tell someone what had happened to him, but it wasn’t the right time to tell everyone.
