It’s curious to note that Jesus frequently orders people and spirits NOT to tell others about his miracles. He would also refer to God’s kingdom as a “secret”, or mystery that’s revealed to only a few. ( Mark 4:10-12)
He may have avoided public recognition for his miracle- working because he didn’t want to be associated with fake, fame- seeking healers. But then again, maybe for it “the mystery” to be revealed for God to be glorified.
