'Mount Ephraim' in the Bible

And Abijah will rise up upon mount Zemaraim, which is in mount Ephraim, and he will say, Hear me, Jeroboam, and all Israel;

And when Asa heard these words, and the prophecy of Oded the prophet, he strengthened himself, and he will put away the abominations from all the land of Judah and Benjamin, and from the cities which he took from mount Ephraim, and he will renew the altar of Jehovah which was before the porch of Jehovah.

And Jehoshaphat will dwell in Jerusalem: and he will turn back and go forth among the people from the Well of the Oath, even to mount Ephraim; and he will turn them back to Jehovah the God of their fathers.
