'Precious' in the Bible

therefore thus saith the Lord Jehovah, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner -'stone of sure foundation: he that believeth shall not be in haste.

And Hezekiah was glad of them, and showed them the house of his precious things, the silver, and the gold, and the spices, and the precious oil, and all the house of his armor, and all that was found in his treasures: there was nothing in his house, nor in all his dominion, that Hezekiah showed them not.

Since thou hast been precious in my sight, and honorable, and I have loved thee; therefore will I give men in thy stead, and peoples instead of thy life.

And I will make thy pinnacles of rubies, and thy gates of carbuncles, and all thy border of precious stones.
