Nehemiah 8:12

And all the people went their way to eat and to drink
Freely and cheerfully:

and to send portions;
to the poor, who had nothing to eat and drink:

and to make great mirth;
with music, vocal and instrumental:

because they had understood the words that were declared unto them;
the meaning of the several laws read and explained unto them, whereby they better understood their duty, and in what instances and in what manner it was to be performed; how much more reason is there for joy and gladness, when the Gospel, and the doctrines of it, are clearly known and understood? ( Psalms 89:15 Psalms 89:16 ) .
