solemnity

And Moses commanded them, saying, At the end of every seven years, in the solemnity of the year of release, in the feast of tabernacles,

Ye shall have a song, as in the night when a holy solemnity is kept; and gladness of heart, as when one goeth with a pipe to come into the mountain of the LORD, to the mighty One of Israel.

And the people besought the Lord, the most High, by prayer before him that is merciful, till the solemnity of the Lord was ended, and they had finished his service.

And they ordained all with a common decree in no case to let that day pass without solemnity, but to celebrate the thirtieth day of the twelfth month, which in the Syrian tongue is called Adar, the day before Mardocheus’ day.
