'Precious' in the Bible

Wail, you shepherds, and cry out.Roll in the dust, you leaders of the flock.Because the days of your slaughter have come,you will fall and become shattered like a precious vase.

Isn’t Ephraim a precious son to Me,a delightful child?Whenever I speak against him,I certainly still think about him.Therefore, My inner being yearns for him;I will truly have compassion on him.This is the Lord’s declaration.
