Nehemiah 8:11

So the Levites stilled all the people
Made them quiet and easy, being backed by the governor:

saying, hold your peace;
refrain from weeping and mourning:

for the day is holy;
a festival, set apart for joy and gladness:

neither be ye grieved;
inwardly; as they were not to show any signs of sorrow outwardly, so they were not to cherish grief inwardly.
