'Precious' in the Bible

Now the boy Samuel was attending to the service of the Lord under the supervision of Eli. The word of the Lord was rare and precious in those days; visions [that is, new revelations of divine truth] were not widespread.

Then Saul said, “I have sinned. Return, my son David, for I will not harm you again because my life was precious in your sight this day. Hear me, I have played the fool and have done a very great wrong [to you].”

Now behold, just as your life was precious in my sight this day, so let my life be precious in the sight of the Lord, and may He rescue me from all distress.”
