And wherever he went — into villages, towns or countryside — they placed the sick in the marketplaces. They begged him to let them touch even the edge of his cloak, and all who touched it were healed — the summary verse generalizes the Gennesaret experience to the entire Galilean campaign: every location (villages, towns, countryside), every person who managed to touch even the edge of his cloak (the hem, the tassel, the minimum contact possible) was healed. The touch of the cloak's edge echoes the bleeding woman's faith in Mark 5:28 — the same faith-contact that produced her healing now characterizes the entire Galilean response.
Church Fathers on Mark 6:56
The Lord remained at the above-mentioned place for some time. Therefore the Evangelist subjoins, 'And when they had come out of the ship, straightway they knew Him,' That is, the inhabitants of the country.
