It is fascinating that at the end of Isaac’s life, he wanted to bless his son Esau instead of Jacob.
One would expect that he would want to bless Jacob, the obedient son. Jacob always followed orders and would be the one to carry on his father’s legacy, along with the principals he stood for. Not Esau, however, who was known to be a wild man, a man with no conscience, let alone a commitment to G-d! Yes, it is true that Esau was a good son in the sense that he would bring his father food, but he was not the son that a dying man would want to bless or to carry on his legacy. So why is it that Isaac looked to bless Esau instead of Jacob?
The Midrash tells us why: Because Esau asked his father a question … and it’s the impetus of this question that caused Isaac to want to bless him.
What did he ask? “How do you tithe salt and straw?”
Now, everyone knows that you do not have to tithe salt or straw; the laws of tithing only apply to things of substance. So isn’t this question a mockery of his father’s devotion to doing what is right, by boasting, “I can be holier than thou?”
Clearly there is a deeper point here that Esau is trying to make. Esau was saying that salt might not have any value on its own, but if you add it to food, the whole dish is enhanced. In essence what he is saying is that one should look beyond just the salt to seek its true potential.
This point did not pass by Isaac unnoticed. Isaac saw the potential in Esau, and wanted to bestow upon him a blessing so that he could achieve his potential. However, Rebekah understood that as great a power the blessing might have, it would not transform him into a better son, since Esau would misuse the blessing (too much salt can ruin the food). Therefore, Rebekah arranged it so that the blessing would go to Jacob instead.
The lesson that we can take from this is that we shouldn’t judge “salt” for what it is, but for what it could be. At the same time, we shouldn’t be blinded by the risk of having too much of something – even if it could enhance our life – if it is something (like salt) that intrinsically can be damaging.
