Daniel 1:17

Dreams. He was learned in all the sciences of the country, like Moses. (Acts vii. 22.) (Calmet) --- They studies these things, in order to refute what was erroneous: discunt....ut judicent. (St. Jerome) --- The Chaldeans paid great attention to dreams. Daniel acquired the knowledge of such as were sent from heaven by the gift of God, as Joseph had done. To pay any regard to common dreams would be childish (Calmet) and sinful, if the person depend on them for the knowledge of futurity. (Haydock)
