The woman with the issue

"Just then a woman who had been subject to bleeding for twelve years came up behind him and touched the edge of his cloak." [Matthew 9:20]

The woman described in Matthew 9:20 had faith. She believed she would be healed if she did but touch the very hem of his garment. If you understand Hebrew thought you'll understand the significance of the story.

Why did the woman touch the hem?

The hem of a Hebrew's prayer shawl is very important. The prayer shawl worn by Hebrew men is called a tallit. The fringe on the corner of the tallit is called a tzitzit. In Numbers 15 God directs the Hebrews to make fringes on the borders (also called corners or wings) of their garments to remind them of God's law!
"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.39You 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." [Numbers 15: 38-39]
There are 613 actual commandments in the Torah-248 positive and 365 negative. Each tzitzit consist of eight strands and five double knots. According to one Jewish numerological tradition, the numerical values of the Hebrew letters for the word for tassel (tzitzit) totalled 600. Six hundred plus eight plus five is 613, the traditional number of biblical commandments. During the first century, a tradition associated with the tallit is that the tzitzit of the Messiah had healing powers. "The Sun of righteousness arise with healing in his wings" [Malachi 4:2].

The woman must have known of this tradition and in faith she touched the wings of His garment showing she believed Jesus is the Messiah!
