Proverbs 25:2-4

²The glory of God is to cover a word; and the glory of kings is to seek out a word. (The glory of God be those things which he hath hidden; and the glory of kings is to search them out.)

³Heaven above, and the earth beneath, and the heart of kings is unsearchable. (The heavens be above, and the earth is beneath, and a king’s heartis unsearchable.)

⁴Do thou away rust from silver, and a full clean vessel shall go out.
