'Assembly' in the Bible

Stop bringing useless offerings! Incense is detestable to me, as are your New Moons, Sabbaths, and calling of convocations. I cannot stand iniquity within a solemn assembly.

You said to yourself:“I will ascend to the heavens;I will set up my throneabove the stars of God.I will sit on the mount of the gods’ assembly,in the remotest parts of the North.

The full moon will be covered up, the bright sun will be darkened; for the Lord who commands armies will rule on Mount Zion in Jerusalem in the presence of his assembly, in majestic splendor.
