'Assemblies' in the Bible

“Bring your worthless offerings no longer,Incense is an abomination to Me.New moon and sabbath, the calling of assemblies—I cannot endure iniquity and the solemn assembly.

then the Lord will create over the whole area of Mount Zion and over her assemblies a cloud by day, even smoke, and the brightness of a flaming fire by night; for over all the glory will be a canopy.
