'Solemn Assembly' in the Bible

The ways of Zion do mourn, because none come to the solemn assembly; All her gates are desolate, her priests do sigh: Her virgins are afflicted, and she herself is in bitterness.

The Lord hath set at nought all my mighty men in the midst of me; He hath called a solemn assembly against me to crush my young men: The Lord hath trodden as in a winepress the virgin daughter of Judah.

And he hath violently taken away his tabernacle, as if it were of a garden; he hath destroyed his place of assembly: Jehovah hath caused solemn assembly and sabbath to be forgotten in Zion, And hath despised in the indignation of his anger the king and the priest.

The Lord hath cast off his altar, he hath abhorred his sanctuary; He hath given up into the hand of the enemy the walls of her palaces: They have made a noise in the house of Jehovah, as in the day of a solemn assembly.

Thou hast called, as in the day of a solemn assembly, my terrors on every side; And there was none that escaped or remained in the day of Jehovah's anger: Those that I have dandled and brought up hath mine enemy consumed.
