'Let There Be' in the Bible

And Nehemiah, who was the Tirshatha, and Ezra, the priest and scribe, and the Levites who were the teachers of the people, said to all the people, This day is holy to the Lord your God; let there be no sorrow or weeping; for all the people were weeping on hearing the words of the law.

Then he said to them, Go away now, and take the fat for your food and the sweet for your drink, and send some to him for whom nothing is made ready: for this day is holy to our Lord: and let there be no grief in your hearts; for the joy of the Lord is your strong place.
