Charles Ellicott Commentary Joshua 16:10

"And they drove not out the Canaanites that dwelt in Gezer: but the Canaanites dwell in the midst of Ephraim unto this day, and are become servants to do taskwork." — Joshua 16:10 (ASV)

They drave not out. —The failure of Ephraim here is noticed, as was the failure of Judah above (Joshua 15:63).
