Targum zu Bereschit 25:29

On the day that Abraham died, Jakob dressed pottage of lentiles, and was going to comfort his father. And Esau came from the wilderness, exhausted; for in that day he had committed five transgressions: he had worshipped with strange worship, he had shed innocent blood, he had gone in unto a betrothed damsel, he had denied the life of the world to come, and had despised the birthright.
