Judges 5:18

Zebulun and Naphtali were a people that jeoparded their lives unto the death in the high places of the field. The men of Zebulun willingly offered their souls, their lives, for the liberation of their country, and those of Naphtali on the heights of their mountainous territory. Their praise, therefore, is sung in this hymn. The soldiers of the Lord who freely set forth to battle with the enemies of Christ, with the weapons of the Spirit, are to be commended, but those who remain idle while their brethren are engaged in campaigns which threaten the very existence of the Church, deserve to be severely reprimanded.
