John Gill Commentary 1 Kings 12:29

"And he set the one in Beth-el, and the other put he in Dan." — 1 Kings 12:29 (ASV)

And he set the one in Bethel
In the southern part of the land, on the border of Ephraim and Benjamin; and the rather he chose this place, because its name signifies the house of God, and had been a sacred place, where Jacob more than once enjoyed the divine Presence:

and the other put he in Dan :
in the northern part of the land, for the convenience of the inhabitants of those parts; and the rather, since it had been a place resorted to in former times, because of the teraphim of Micah there.
