“As the [prayer shawl] was placed over the head, it formed its own tent. WINGS of the garment were formed when the arms were held out. For this reason, the corners of the prayer shawl are often called "wings." During the first century there were several traditions associated with the tzitzit [fringes]concerning Messiah. One was that these knotted fringes possessed healing powers. Certainly the woman with the issue of blood knew of these traditions, which would explain why she sought to touch the hem (the wings) of Jesus’ prayer garment. The same word used in Numbers 15:38 for corner is used in Malachi 4:2 for wings. With this understanding in mind, an ancient Jew under the prayer shawl could be said to be dwelling in the secret place of the Most High and under His wings (Ps. 91:1-4). The lady with the issue knew that if Jesus were the promised Messiah, there would be healing in His wings (fringes). That this was the opinion of many other people is revealed by the crowd who sought his healing powers, ‘that they might only touch the hem of his garment: and as many as touched were made perfectly whole,’ Matthew 14:36.” [http://www.hopeofisrael.net]
