Nehemiah 4:20

In what place therefore ye hear the sound of the trumpet
Be it what part of the wall soever they were at work, even the most distant:

resort ye thither to us;
to Nehemiah, and the half of his servants armed, where the trumpet was blown; that was to be the place of rendezvous:

our God shall fight for us;
and give us victory over our enemies; none have any reason to be intimidated, when they shall hear the sound of the trumpet.
