“Lest there bee any fornicatour, or profane person, as Esau, who for one morsell of meat sold his birthright.”
1611 King James Version (KJV)
12:16 Esau was profane for so slighting the blessing which went along with the birth - right.
Heb 12:16 Lest there [be] any fornicator. Of course such a sinner would not live the life of holiness enjoined. Or profane person. A worldly person who profanes holy privileges by placing on them a worldly estimate. As Esau. See Ge 25:27-30. He illustrates what is meant by a profane person. Who for one morsel of meat sold his birthright. For a savory meal he bartered away a birthright bestowed by God. So any professing Christian who would sell his heavenly birthright for worldly advantages would be a profane person.
