The fear of the Lord is his treasure.

«Woe to thee that spoilest, and thou wast not spoiled; and dealest treacherously, and they dealt not treacherously with thee! when thou shalt cease to spoil, thou shalt be spoiled; and when thou shalt make an end to deal treacherously, they shall deal treacherously with thee. O Lord, be gracious unto us; we have waited for thee: be thou their arm every morning, our salvation also in the time of trouble. At the noise of the tumult the people fled; at the lifting up of thyself the nations were scattered. And your spoil shall be gathered like the gathering of the caterpiller: as the running to and fro of locusts shall he run upon them. The Lord is exalted; for he dwelleth on high: he hath filled Zion with judgment and righteousness. And wisdom and knowledge shall be the stability of thy times, and strength of salvation: the fear of the Lord is his treasure.»
