Just

in case people didn't know
what the biblical usage of "Understanding" meant.

Psalm 49:20

People who have wealth but lack understanding
    are like the beasts that perish.

Job 28:28 

And he said to the human race,
    “The fear of the Lord—that is wisdom,
    and to shun evil is understanding.”

Proverbs 9:10 

The fear of the Lord is the beginning of wisdom,
    and knowledge of the Holy One is understanding.
