1st Kings 12:28

25 Then Jeroboam made the town of Shechem in the hill-country of Ephraim a strong place, and was living there; and from there he went out and did the same to Penuel.

26 And Jeroboam said in his heart, Now the kingdom will go back to the family of David:

27 If the people go up to make offerings in the house of the Lord at Jerusalem, their heart will be turned again to their lord, to Rehoboam, king of Judah; and they will put me to death and go back to Rehoboam, king of Judah.

28 So after taking thought the king made two oxen of gold; and he said to the people, You have been going up to Jerusalem long enough; see! these are your gods, O Israel, who took you out of the land of Egypt.

29 And he put one in Beth-el and the other in Dan.

30 And this became a sin in Israel; for the people went to give worship to the one at Beth-el, and to the other at Dan.

31 And he made places for worship at the high places, and made priests, who were not Levites, from among all the people.
