Noah’s sons – No’ach
Shem (“name”) is an intellectual who can define and identify things, Cham (“warmth”) is emotional and passionate, and Yefet (“beauty”) represents artistic creativity.
Though we customarily list them in that order, Shem, Cham and Yefet, the wording of Gen. 10:21 suggests that the oldest son is Yefet, so why do we normally put Shem first?
The Talmud (Sanh. 108b) calls Shem “the great one”. It was he who took the initiative of covering his father who was inebriated and naked, making him the most morally sensitive of the brothers. The sages say that Shem thus typifies the Jewish people whose tradition is that every moral and ethical problem should be responded to with speed, energy and conscience.
The rabbis had a poor opinion of Cham whom they regarded as symbolic of the callousness and unconcern which were the hallmarks of his son Canaan and his later descendants.
