1Cor.5.8  Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
Col.2.16  Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath.
