And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance for ever throughout your generations.
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.
And Moses said, Wherefore now do ye transgress the commandment of the LORD? but it shall not prosper.
For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you.
He is wise in heart, and mighty in strength: who hath hardened himself against him, and hath prospered?
But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God.
