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

16:20-63 Here is a list of the cities of Judah. But we do not here find Bethlehem, afterwards the city of David, and ennobled by the birth of our Lord Jesus in it. That city, which, at the best, was but little among the thousands of Judah, Mic 5:2, except that it was thus honoured, was now so little as not to be accounted one of the cities.The verb "were," introduced by the King James Version in this verse should be omitted; and the full stop after Joshua 16:8 replaced by a colon. The purport of Joshua 16:9 is simply to add to the inheritance of Ephraim, defined by the preceding context, "the separate cities" or more properly "single cities" which were allotted to them in addition within the borders of Manasseh. The reasons for granting these additional cities to the Ephraimites can only be conjectured. Perhaps the territory assigned to this numerous tribe proved on experiment to be too small; and therefore some towns, which are named in 1 Chronicles 7:29, were given to them from the kindred Manassites, the latter being recompensed (Joshua 17:11 note) at the expense of Issachar and Asher. 10. they drave not out the Canaanites … but the Canaanites dwell among the Ephraimites unto this day, and serve under tribute—This is the first mention of the fatal policy of the Israelites, in neglecting the divine command (De 20:16) to exterminate the idolaters. The Canaanites were not driven out until Solomon’s time, 1 Kings 9:16.

Under tribute, as Joshua 17:13 1 Kings 9:16.

And they drove not out the Canaanites which dwelt in Gezer,.... Which was the border of their tribe length ways, and was near the sea, Joshua 16:3; in this they did not obey the command of God, and either they did not drive them out, because they could not, God not delivering them up into their hands, because of their sins; or through their slothfulness, or it may be through covetousness, being willing to make some advantage to themselves by them, being a trading people, which seems to be intended in the next clause:

but the Canaanites dwelt among the Ephraimites unto this day; which Joshua, the writer of this book, might truly say, and be no objection to it, since the same is observed after his death, Judges 1:29; and indeed they continued to dwell there until the times of Solomon, when it was taken by Pharaoh king of Egypt, and given as a present to his daughter, the wife of Solomon, 1 Kings 9:15; and though this clause does not furnish out an argument against the writing of this book by Joshua, yet, from the instance given, it appears it must have been written before the times of Solomon, and so not by Ezra, as some:

and serve under tribute; so that they were under their power, and therefore could have driven them out, or slain them, as by the command of God they should; but they spared them for the sake of the tribute they received from them, which seems to agree with the character of the Ephraimites, Hosea 12:8.

And they drave not out the Canaanites that dwelt in Gezer: but the Canaanites dwell among the Ephraimites unto this day, and serve under tribute.
