Halakhah sa Exodo 34:17: Mishneh Torah, Negative Mitzvot & Mishneh Torah, Rest

Not to make a graven image; neither to make it oneself not to have it made by others, as it is said, “Thou shalt not make unto thee any graven image” (Ex. 20:4).

Not to make idols even for others, as it is said, “Thou shalt not make unto thee molten gods” (Ex. 34:17).

In the same way that there is an obligation to honor the Sabbath and to delight in it, so too [is it with] the holidays. As it is stated (Isaiah 58:13) "to sanctify the honored Lord"; and it is stated about all of the holidays (Leviticus 23:7), "a time of holiness." And we have already explained [this] honoring and delighting in the laws of the Shabbat. It is therefore fit for a person to refrain from having a meal on the eve of holidays from the time of the afternoon prayer, like on the eve of Shabbat. As this thing is part of [its] honor. And anyone who disgraces the festivals is as if he was associated with idolatry.
