Numbers

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 offered upon 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 which he had made.

He appointed also the king’s portion of his substance for the burnt offerings, to wit, for the morning and evening burnt offerings, and the burnt offerings for the sabbaths, and for the new moons, and for the set feasts, as it is written in the law of the Lord.
