Exodus 32:5

²⁰Jehu said, “Sanctify a solemn assembly for Baal!” So they proclaimed it.

²“Speak to the children of Israel, and tell them, ‘The set feasts of the LORD, which you shall proclaim to be holy convocations, even these are my set feasts.

³⁷“‘These are the appointed feasts of the LORD which you shall proclaim to be holy convocations, to offer an offering made by fire to the LORD, a burnt offering, a meal offering, a sacrifice, and drink offerings, each on its own day—

⁴“‘These are the set feasts of the LORD, even holy convocations, which you shall proclaim in their appointed season.

³²Jeroboam ordained a feast in the eighth month, on the fifteenth day of the month, like the feast that is in Judah, and he went up to the altar. He did so in Bethel, sacrificing to the calves that he had made, and he placed in Bethel the priests of the high places that he had made. ³³He went up to the altar which he had made in Bethel on the fifteenth day in the eighth month, even in the month which he had devised of his own heart; and he ordained a feast for the children of Israel, and went up to the altar to burn incense.

⁴He received what they handed him, fashioned it with an engraving tool, and made it a molded calf. Then they said, “These are your gods, Israel, which brought you up out of the land of Egypt.”

¹¹Because Ephraim has multiplied altars for sinning, they became for him altars for sinning.

⁵So they established a decree to make proclamation throughout all Israel, from Beersheba even to Dan, that they should come to keep the Passover to the LORD, the God of Israel, at Jerusalem, for they had not kept it in great numbers in the way it is written.

²¹You shall make proclamation on the same day that there shall be a holy convocation to you. You shall do no regular work. This is a statute forever in all your dwellings throughout your generations.

⁸Therefore let’s keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.
