And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them. Deuteronomy 20:3 (KJV)
"Dies Irae, Dies Illa"--the Day of Wrath may be at hand.
But do not fear:
"Yes, Lord God Almighty,
true and just are your
judgements."
Revelation 16:7b
