Nehemiah

Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times.

Therefore set I in the lower places behind the wall, and on the higher places, I even set the people after their families with their swords, their spears, and their bows.

If when he seeth the sword come upon the land, he blow the trumpet, and warn the people;

And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the Lord your God, and ye shall be saved from your enemies.
