As the literal statement is plain enough, we need only consider the inner meaning, which was meant to be interpreted in this manner. The law of the Chaldaeans taken symbolically is mathematical speculation, one part of which is recognised to be astronomy, which the Chaldaeans study with great industry and with great success. Therefore God is here honouring the wise man with a gift; in the first place, by taking men out of the sect of the astrologers, that is to say, away from the hallucinations of the Chaldaeans, which, as they are difficult to detect and refute, are found to be the cause of great evils and wickedness, since they ascribe the attributes of the Creator to created things, and persuade men to worship and to venerate the works of the world as God.
In the second place, God honours him by granting to him the wisdom which bears fruit, which he has here symbolically called the earth; but the Father of the universe shows that wisdom and virtue are invariable and immutable, since it is not consistent with his character that God should show to any one that which can undergo any variation or change, for that which is shown by the being who is immutable and consistent must be so too; but that which is liable to change, as being incessantly in the habit of suffering variation, admits of no proper or divine demonstration.
