Genesis 25:34
Then Jacob gave Esau bread and pottage of lentiles; and he did eat and drink, and rose up, and went his way: thus Esau despised his birthright.
Then Jacob gave Esau bread and pottage of lentiles,.... This shows what the pottage was made of, of which see Genesis 25:30; and that Jacob gave to Esau more than he asked and bargained for, bread as well as pottage; but neither of them until the bargain was made and swore to, and be had got the birthright secured unto him; as cunning as Esau, and as simple and plain as Jacob were, the latter outwitted the former, and was too crafty for him:
and he did eat, and drink, and rose up, and went his way; following his former course of life, without any remorse of conscience, reflection of mind, or repentance for what he had done; for though he afterwards carefully sought the blessing with tears he had parted with, yet not until his father was upon his deathbed, Hebrews 12:17;
thus Esau despised his birthright; by setting it at so mean a price, and by not repenting of it when he had so done; having no regard especially to spiritual blessings, to the Messiah, and to the heavenly inheritance, eternal glory and happiness by Christ: the Jerusalem Targum adds,
"and he despised his part in the world to come, and denied the resurrection of the dead;''
and the Targum of Jonathan on Genesis 25:29 says, that
"on that day he committed five transgressions; he performed strange worship (or committed idolatry), he shed innocent blood, he lay with a virgin betrothed, he denied the life of the world to come (or a future state), and despised the birthright;''
which confirms the character the apostle gives of him, that he was a fornicator and a profane person, Hebrews 12:16.
