They were given these cities of refuge: Shechem with its surrounding suburbs in the hill country of Ephraim, Gezer with its surrounding suburbs,

Their possessions and settlements included Bethel and its towns, Naaran to the east, Gezer and its towns to the west, Shechem and its towns as far as Ayyah and its towns

So David did just as God had ordered, and they struck down the Philistine army from Gibeon to Gezer.

Afterwards, war broke out against the Philistines at Gezer, where Sibbecai the Hushathite killed Sippai, one of the descendants of the Rephaim, defeating the Philistines.
