'Feast days' in the Bible

I will also cause all her mirth to cease, her feast days, her new moons, and her sabbaths, and all her solemn feasts.

“And I will punish her for the [feast] days of the Baals,When she used to offer sacrifices and burn incense to themAnd adorn herself with her earrings and nose rings and her jewelry,And follow her lovers, so that she forgot Me,” says the Lord.

Yet am I the LORD thy God, even as when I brought thee out of the land of Egypt, and set thee in thy tents, and as in the high feast days.
