'Precious' in the Bible

So Ahaziah again sent a captain of a third fifty with his fifty [fighting men]. And the third captain of fifty went up and came bowed down on his knees before Elijah, and begged him [for compassion] and said to him, “O man of God, please let my life and the lives of your servants, these fifty, be precious in your sight.

Behold, fire came down from heaven and consumed the first two captains of fifty with their fifties; but now let my life be precious in your sight.”

Hezekiah listened to and welcomed them and [foolishly] showed them all his treasure house—the silver and gold and spices and precious oil and his armory and everything that was found in his treasuries. There was nothing in his house (palace) nor in all his realm that Hezekiah did not show them.
