'Assembly' in the Bible

Sanctify a fast, call a solemn assembly, gather the old men and all the inhabitants of the land unto the house of Jehovah your God, and cry unto Jehovah.

Blow the trumpet in Zion, sanctify a fast, call a solemn assembly;

gather the people, sanctify the assembly, assemble the old men, gather the children, and those that suck the breasts; let the bridegroom go forth from his chamber, and the bride out of her closet.
