'Assemblies' in the Bible

Bring no more vain oblations; incense is an abomination unto me; new moon and sabbath, the calling of assemblies,- I cannot away with iniquity and the solemn meeting.

And Jehovah will create over the whole habitation of mount Zion, and over her assemblies, a cloud and smoke by day, and the shining of a flaming fire by night; for over all the glory'shall be spread a covering.
