Matthew Poole and continuators on Genesis 25:30

30 And Esau said to Jacob, feed me, I pray thee, with that same red pottage, for I am faint: therefore was his name called Edom .

Red by the infusion of Lentiles, or Saffron, or some other things of that colour. The word is doubled in the Hebrew text to shew how vehemently he desired it.

Which signifies red, as he was at first so called from the colour of his hair, so now that name was confirmed and given to him afresh upon this occasion, q. d. He was rightly called Edom or red, not onely historically for his colour, but prophetically for this accident.

Marginal references: Heb. with that red, with that pottage.
