Esau accosted Jacob thus, "Why art thou preparing lentils?"
Jacob: "Because our grandfather passed away; they shall be a sign of my grief and mourning, that he may love me in the days to come."
Esau: "Thou fool! Dost thou really think it possible that man should come to life again after he has been dead and has mouldered in the grave?" He continued to taunt Jacob. "Why dost thou give thyself so much trouble?" he said. "Lift up thine eyes, and thou wilt see that all men eat whatever comes to hand--fish, creeping and crawling creatures, swine's flesh, and all sorts of things like these, and thou vexest thyself about a dish of lentils."
