“Now Isaac loved Esau, because he had a taste for game, but Rebekah loved Jacob.”  Gen. 25:28

Favoritism of a child by the father is a running motif in the the book of Genesis.  Here we see that Isaac loves Esau.  Looking back to Abraham, it appears he favored Ishmael (Gen. 17:18 “Oh that Ishmael may live before you!” and Gen. 21:11 where Abraham did not want to send Hagar and Ishmael away, “on account of his son”).  Even going back as far as Cain and Abel, God had regard for Abel’s offering, but not Cain’s.  Not that God was necessarily being partial, but it was perceived that way by Cain.   Looking forward we see Joseph with his coat of many colors.

In the original Hebrew it is not clear as to who had a “taste for game”, it may have been Esau.  Another rendering may be ” he had a taste for trappings in his mouth”.  Thus, because Esau liked to hunt and Isaac liked to eat it, Esau was the favorite in his eyes.

We must note the Hebrew play on words in the phrase “a taste for trappings in his mouth.” which may indicate deceitful words of Esau that were pleasing to Isaac’s ears.  There are rabbinical stories about Esau pretending to be pious to his father.
