"We often refer to wise discoveries as gold, as the Lord says, speaking through the Prophet:
'I gave to them gold and silver.' [Hosea 2:8] Daniel says of the wise: 'If you sleep among the midst of the lots,
you shall be as the wings of the dove covered with silver and the hinder parts of her back like to gold.'
[Ps 67:14] In this way one who puts his trust in the aid of the Old and New Testament can by resourceful inquiry attain the inmost secrets of the Wisdom of God."
