Jesus said, "Who touched me?"
When all denied it, Peter and those with him said,
"Master, the multitudes press and jostle you, and you say, ‘Who touched me?’"
But Jesus said, "Someone did touch me,
for I perceived that power has gone out of me."
When the woman saw that she was not hidden, she came trembling,
and falling down before him declared to him in the presence of all the people
the reason why she had touched him, and how she was healed immediately.
He said to her, "Daughter, cheer up.
Your faith has made you well. Go in peace."
What does this reveal about Jesus?
Contacting Jesus by faith can bring healing.
This woman had been in a continuous unclean state therefore must have been treated to some degree like a leper.
Leviticus 15:25-27 "'When a woman has a discharge of blood for many days at a time other than her monthly period or has a discharge that continues beyond her period, she will be unclean as long as she has the discharge, just as in the days of her period. Any bed she lies on while her discharge continues will be unclean, as is her bed during her monthly period, and anything she sits on will be unclean, as during her period. Whoever touches them will be unclean; he must wash his clothes and bathe with water, and he will be unclean till evening.""The hem or fringe of a garment which the woman touched was a tassel or tuft hanging from the edge of the outer garment according to Nu 15:38. It was made of twisted wool. Jesus wore the dress of other people with these fringes at the four corners of the outer garment." (RWP)
It is insightful to consider the purpose of such a tassel:
Numbers 15:38-40 "Speak to the Israelites and say to them: 'Throughout the generations to come you are to make tassels on the corners of your garments, with a blue cord on each tassel. You will have these tassels to look at and so you will remember all the commands of the LORD, that you may obey them and not prostitute yourselves by going after the lusts of your own hearts and eyes. Then you will remember to obey all my commands and will be consecrated to your God."It was blue because that was the color of the curtain in the temple and previously in the tabernacle.
Although there was no promise concerning healing by touching this tassel, yet recognizing the appropriate symbolism and wanting to consecrate her body to God she simply stepped out in faith. I would imagine her reasoning might be that Jesus couldn't possibly become unclean, so anyone unclean touching him must automatically become clean. I don't perceive that it was the reaching out and touching his garment which was the object of her faith in particular. But rather it was a sort non-verbal way of asking for healing, much as a child would tug at their mother's skirt.
The context is significant when it comes to application. For there are those today, particularly in the Word-Faith Movement who will make up their own arbitrary make-believe promise and put their faith in that, whereas this woman was acting in accordance with the spirit of the Law and in accordance with the spirit of Christ as the context dictated.
I also perceive that Jesus was not really ignorant of who had touched him, but rather to complete the healing of her social relationships by making her healing publicly known. Thus she would no longer be reckoned unclean. For prior to this she had thought only to sneak up unnoticed possibly due to social pressure she had experience for many years.
