Learning from one’s teacher[1]
ויאמר אם-יבוא עשו אל-המחנה האחת והכהו והיה המחנה הנשאר לפליטה
[Yaakov] said: “If Eisav comes to one of the camps and strikes them, the remaining camp will survive”[2]
During the sovereignty of Achav, the wicked King of Israel, the prophet Ovadiah had to protect himself and all the other prophets from his reign of terror. The verse says[3] Ovadiah took one hundred prophets and hid fifty of them in a cave. Chazal ask[4] why didn’t he put them all in the cave? Rabbi Elazar answers that Ovadiah learned this strategy from Yaakov. When Yaakov and his family were about to confront his wicked brother Eisav, he divided his camp into two. This tactic was in case of the horrible event that one of the two camps is killed, at least the other one would survive. Why did the gemarra need to say that Ovadiah learned this strategy from Yaakov? Simply say that he thought of the idea himself[5]!
