The New Testament of the Bible records more than one miracle in which Jesus healed people who were blind. In John 9:1-41, Jesus mixes saliva with dirt and spreads the mud on the blind person's eyes and he is miraculously able to see. The Gospel of Mark describes another miracle in which Jesus puts saliva on a man's eyes:
He looked up and said, "I see people; they look like trees walking around."
Once more Jesus put his hands on the man's eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly. Jesus sent him home, saying, "Don't even go into the village."
- Mark 8:22-26, NIV translation.
