Берешит 25:27 Комментарий: Tze'enah Ure'enah, Rashi, Chizkuni & Da'at Zekenim

“When the boys grew up, Esau became a skillful hunter” [25:27]. It cannot be recognized when people are children if they will become pious or evil. However, when they became thirteen years old, Esau went to the house of idols and Jacob went to the house of study.²²Rashi, Genesis, 25:27.

“A skillful hunter” [25:27]. Esau was a deceiver and he deceived people with his mouth. He asked his father how one tithed salt and straw. Isaac thought that Esau was very pious. He even tithed salt and straw.²³Ibid.

“Jacob was a mild man who stayed in camp” [25:27]. Jacob was not a scoundrel and he could not deceive. He studied Torah day and night. Isaac loved Esau because he brought him meat from the hunt, and Rebecca loved Jacob.²⁴Rashi, Genesis, 25:27–28.

ויגדלו… ויהי עשו AND THEY GREW … AND ESAU WAS — So long as they were young they could not be distinguished by what they did and no one paid much attention to their characters, but when they reached the age of thirteen, one went his way to the houses of learning and the other went his way to the idolatrous temples (Genesis Rabbah 63:10).
