Why did Esau get so excited about missing the blessing but not care about losing the birthright?
Esau became upset over the missing blessing because it was material and tangible, while the birthright never troubled him because it was spiritual. His grief focused on the physical benefit he lost, not the spiritual privilege he had already treated lightly.
Les explains that the blessing was something material, so Esau got so excited about missing it because he was focused on that tangible loss. The birthright, however, never bothered him because it was something spiritual. This contrast shows Esau’s value system: the material blessing stirred him, while the spiritual birthright did not, even though the birthright was the greater spiritual matter.
