New King James Version (NKJV)
Further Wise Sayings of Solomon
25 These also are proverbs of Solomon which the men of Hezekiah king of Judah copied:
2 It is the glory of God to conceal a matter,
But the glory of kings is to search out a matter.
3 As the heavens for height and the earth for depth,
So the heart of kings is unsearchable.
