31. Jeroboam built small places of worship at the shrines and appointed men who were not from the tribe of Levi to serve as priests.

32-33. He also decided to start a new festival for the Israelites on the fifteenth day of the eighth month, just like the one in Judah. On that day, Jeroboam went to Bethel and offered sacrifices on the altar to the gold calf he had put there. Then he assigned the priests their duties.
