A.T. Robertson Commentary Mark 5:14

"And they that fed them fled, and told it in the city, and in the country. And they came to see what it was that had come to pass." — Mark 5:14 (ASV)

And in the country (κα εις τους αγρους). Mark adds this to "the city." In the fields and in the city as the excited men ran they told the tale of the destruction of the hogs. They came to see (ηλθον ιδειν). All the city came out (Matthew), they went out to see (Luke).
