For U.S citizens Valor is one of our most sacred words. The word appears on our 3 highest combat medals, including the Medal of Honor, awarded to brave soldiers for heroic combat service.
The modern definition of valor is: exceptional or heroic courage when facing danger. Old Testament Hebrew adds the concept of worth or value to the definition, but not in the sense of economic riches. It points to the value of the individual’s character and actions for the community he serves. A person might be rich, but riches can’t buy valor.
The word also carries moral weight. A criminal might be daring, but that is not Valor. Valor is a moral virtue. It also is not used in the Bible exclusively for men or for bravery in battle. It is translated “virtuous” when used of Ruth, and the woman in Proverbs 31.
In the Scriptures it seems to be reserved for people who show uncommon firmness, strength, and character in the face of extreme opposition. While it properly is used for our brave soldiers, police officers, and fire fighters, it could also be used for those who willingly sacrifice their lives and/or overcome great personal obstacles for the sake of others.
