1 Kings 12:25

Then Jeroboam built Shechem in Mount Ephraim, and dwelt
therein
Not that this city had lain in ruins from the times of Abimelech, ( Judges 9:45 ) for then it would not have been a proper place for the convention of the people, ( 1 Kings 12:1 ) but he repaired the walls of it, and fortified it, and built a palace in it for his residence:

and went out from thence, and built Penuel;
a place on the other side Jordan, the tower of which was beaten down by Gideon, ( Judges 8:17 ) and might be now rebuilt, or at least the city was repaired by him, and anew fortified, perhaps for the better security of his dominions on that side Jordan; though Fortunatus Scacchus ^F16 is of opinion that this was an altar, the same as at Carmel, ( 1 Kings 18:30 ) , which Jeroboam built, and called by this name in testimony of the common religion of the Israelites and Jews.
