A.T. Robertson Commentary Mark 5:28

"For she said, If I touch but his garments, I shall be made whole." — Mark 5:28 (ASV)

If I touch but his garments (Εαν αψωμα κ'αν των ιματιων αυτου). She was timid and shy from her disease and did not wish to attract attention. So she crept up in the crowd and touched the hem or border of his garment (κρασπεδον) according to Mt 9:20 and Lu 8:44.
