Deuteronomy 9:2

Ver. 2. Who can stand before the children of Anak!— The strength and valour of this people were so great, that they became proverbial. They were vanquished by Joshua, who made them flee to the Philistines, where, it should seem, a remnant of them lived till the time of David; for Goliah and his brethren appear to have been Anakims, 1 Chronicles 20:6 being all born at Gath, whither the Anakims fled. 2 Samuel 21:22.Joshua 11:22. Some critics think, that from the word Anak the Greeks derived their anax, or king, taken from the idea of the power and greatness of these men, some of whom, it is probable, passed into Greece when they were driven out of their own country by Joshua.
