'Assemblies' in the Bible

Bring no more vain offerings. Incense is an abomination to me; new moons, Sabbaths, and convocations: I can't bear with evil assemblies.

Yahweh 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 will be a canopy.
