Genesis 25:29

And Jacob sod pottage: and Esau came from the field, and he was faint:

Jacob sod pottage - a soup made of a decoction of lentiles or small beans, called 'Adas (cf. 2 Samuel 17:28), which is very common in Egypt and Syria, particularly among country people and natives when traveling (Robinson's 'Biblical Researches'). It is probable that Jacob made use of Egyptian beans, which he had procured as a dainty; because Esau was a stranger to it; and hence, he said, 'Feed me, I pray thee, with that red, red (thing).' The Hebrew, "red," includes the idea of a brown or chocolate colour. This lentile soup is very palatable, particularly when accompanied with melted butter and pepper; and to the weary hunter, faint through hunger, the odour of the smoking dish must have been irresistibly tempting.
