Genesis 25:28

And Isaac loved Esau, because he did eat of his venison: but Rebekah loved Jacob.

The parents were divided in their affection; and while the grounds, at least, of the father's partiality were weak, the distinction made between the children led, as such conduct always does, to unhappy consequences.

Because he did eat of his venison - literally, because venison was in his mouth; i:e., he was fond of game. [But the Septuagint has: hoti hee theera autou broosis autoo-for his (Esau's) venison was food to him.]
