Thus it was Elijah who taught Rabbi Jose the deep meaning hidden in the Scriptural passage in which woman is designated as the helpmeet of man. By means of examples he demonstrated to the Rabbi how indispensable woman is to man.
Rabbi Nehorai profited by his exposition of why God created useless, even noxious insects. The reason for their existence is that the sight of superfluous and harmful creatures prevents God from destroying His world at times when, on account of the wickedness and iniquity prevailing in it, it repents Him of having created it. If He preserves creatures that at their best are useless, and at their worst injurious, how much more should He preserve human beings with all their potentialities for good.
