Musar para sa Genesis 26:12

On Genesis 26,12: ויזרע יצחק בארץ ההיא וימצא בשנה ההיא מאה שערים, ויברכהו ה', Bereshit Rabbah 64,6 comments and Rashi quotes that the meaning of מאה שערים is one hundred times what was reasonably to be expected. Rashi adds: "our sages say that this estimate was necessary in order to determine the amount of tithes to be given from that harvest."

Rebeccah concluded that there was no point in living a life that was measured by the yardstick of the undiluted מדת הדין, seeing that hardly anyone could survive if he were to be measured by that attribute alone. This is why she said: קצ-תי בחיי, i.e. what good is my life under such circumstances! (Genesis 27,46) Unless some relief is found for the rest of the world's population this is the end of meaningful life. She referred to the tribe of חת, a Canaanite tribe whose daughters Esau had married. Seeing that the Canaanites were cursed already and that Esau himself was an outgrowth of the סטרא אחרא, she considered the combination as lethal, bound to lead to the oblivion of their offspring. Because of such considerations, the name that should by rights have been קצחי was changed to יצחק, to introduce the element of joy into their lives. The immediate cause for this was Isaac giving tithes which resulted in G–d blessing his efforts, as related in 26,12. It is strange that when Malachi 3,10 describes the blessing that results from tithing, he uses the expression of ארובות השמים, "the windows of heaven." Since the Torah uses the same expression at the onset of the deluge in Genesis 7,11, we wonder why the prophet would use an expression to symbolize blessing when that same expression had symbolized a curse on mankind in its prior usage in the Bible.
