'Hill Country Of Ephraim' in the Bible

And there was a certain man, of Ramathaim-zuphi, of the hill country of Ephraim, - whose name, was Elkanah, son of Jeroham, son of Elihu, son of Tohu, son of Zuph, an Ephraimite;

And he passed through the hill country of Ephraim, and passed through the land of Shalishah, but they found them not, - then passed they through the land of Shaalim, and they were not there, then passed he through the land of the Benjamites, but they found them not.

And, all the men of Israel who had hidden themselves throughout the hill country of Ephraim, heard that the Philistines had fled, and, they also, followed hard after them in the battle.
