1 Kings 12:32

EJ2000(i) 32 Then Jeroboam ordained a solemnity in the eighth month, on the fifteenth day of the month, like unto the solemnity that was celebrated in Judah; and he sacrificed upon the altar. So did he in Bethel, sacrificing unto the calves that he had made. He also ordered in Bethel the priests of the high places which he had made.
