TSK · Leviticus 23:33

Jeroboam inaugurated a festival on the fifteenth day of the eighth month, like the festival celebrated in Judah. On the altar in Bethel he offered sacrifices to the calves he had made. In Bethel he also appointed priests for the high places he had made.

In the seventh month, on the fifteenth day of the month, at the feast, he will make the same provisions for the sin offering, burnt offering, and grain offering, and for the olive oil, for the seven days.
