Philo: On Sobriety

VII. (31) We must now then consider whom the wise man here curses; for this is one of the matters especially deserving of investigation, since he curses not the son who appears to have done the wrong, but his son, and his own grandson, of whom he has not mentioned any apparent sin at present, either small or great; (32) for the who from superfluous curiosity wished to see his father naked, and who laughed at what he saw, and who divulged what ought properly to have been concealed in silence, was Ham, the son of Noah; but he who bears the blame for the offences committed by the other, and who reaped the fruit of them in curses is Canaan; for it is said, "Cursed is Canaan the son, the servant, the servant of servants, shall he be to his Brethren."

(33) And yet, as I said before, what sin had he committed? But they, who are accustomed to explain the formal, and literal, and obvious interpretations of the laws have perhaps considered this by themselves; but we, being guided by right reason, as it suggest itself to us, will interpret it according to the explanation which is ready to hand, having just made this necessary preface.
