Proverbs 25:2-5

²The glory of God is to cover a word; and the glory of kings is to seek out a word.

³Heaven above, and the earth beneath, and the heart of kings is unsearchable.

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

⁵Do thou away unpiety from the cheer of the king, and his throne shall be made steadfast by rightfulness or rightwiseness.
