'Assemblies' in the Bible

"Tell the Israelis that these are my festival times appointed by the LORD that you are to declare as sacred assemblies:

These are the LORD's appointed festivals and sacred assemblies that you are to declare at their appointed time.

"These are the LORD's appointed festivals that you are to proclaim as sacred assemblies. Bring offerings made by fire to the LORD a whole burnt offering, a meal offering, a sacrifice, and drink offerings. Do this every day on its assigned date

I'll put a stop to her mirth, along with her celebrations, her New Moons, her Sabbaths, and all of her festive assemblies.
