Genesis 25:29-31 Amplified Bible, Classic Edition (AMPC)
29 Jacob was boiling pottage (lentil stew) one day, when Esau came from the field and was faint [with hunger].
30 And Esau said to Jacob, I beg of you, let me have some of that red lentil stew to eat, for I am faint and famished! That is why his name was called Edom [red].
31 Jacob answered, Then sell me today your birthright (the rights of a firstborn).
