Proverbs 20:5

20:5 Counsel in a person’s heart is like deep water,

but an understanding person draws it out.

Proverbs 25:2-3

25:2 It is the glory of God to conceal a matter,

and it is the glory of a king to search out a matter.

25:3 As the heaven is high and the earth is deep

so the hearts of kings are unsearchable.
