TSK · Leviticus 23:33

And Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like unto the feast that is in Judah, and he went up unto the altar; so did he in Beth-el, sacrificing unto the calves that he had made: and he placed in Beth-el the priests of the high places that he had made.

In the seventh [month], in the fifteenth day of the month, in the feast, shall he do the like the seven days; according to the sin-offering, according to the burnt-offering, and according to the meal-offering, and according to the oil.
