Nehemiah 8:11 (KJV)

And Nehemiah, which is the Tirshatha, and Ezra the priest the scribe, and the Levites that taught the people, said unto all the people, This day is holy unto the Lord your God; mourn not, nor weep. For all the people wept, when they heard the words of the law.

Then he said unto them, Go your way, eat the fat, and drink the sweet, and send portions unto them for whom nothing is prepared: for this day is holy unto our Lord: neither be ye sorry; for the joy of the Lord is your strength.

So the Levites stilled all the people, saying, Hold your peace, for the day is holy; neither be ye grieved.

And all the people went their way to eat, and to drink, and to send portions, and to make great mirth, because they had understood the words that were declared unto them.

And on the second day were gathered together the chief of the fathers of all the people, the priests, and the Levites, unto Ezra the scribe, even to understand the words of the law.
