Nehemiah 4:14

and having taken a view, I arose and said to the nobles, and to the officers, and to the rest of the people, Be not afraid of them. Remember our God Who is great and terrible; and fight for your brethren, your sons, your daughters, your wives and your houses.

In whatsoever place ye shall hear the sound of the cornet, thither gather yourselves together to us; and our God shall fight for us.
