창세기 2:18의 주석

'לא טוב היות וגו IT IS NOT GOOD etc. — I shall make an help meet for him in order that people may not say that there are two Deities, the Holy One, blessed be He, the only One among the celestial Beings without a mate, and this one (Adam), the only one among the terrestrial beings, without a mate (Pirkei D'Rabbi Eliezer 12).

IT IS NOT GOOD THAT THE MAN SHOULD BE ALONE. It does not appear likely that man was created to be alone in the world and not beget children since all created beings — male and female of all flesh — were created to raise seed. The herb and trees also have their seed in them. But it is possible to say that it was in accordance with the opinion of the Rabbi who says:³⁶⁰Berachoth 61a. The name of the Rabbi is Yirmeyahu the son of Rabbi Elazar. “Adam was created with two faces [i.e., male and female persons combined],” and they were so made that there should be in them an impulse causing the organs of generation to produce a generative force from male to female, or you may say “seed,” in accordance with the known controversy concerning pregnancy,³⁶¹See Ramban, beginning of Seder Thazria concerning the opinion of the doctors and the Greek philosophers. and the second face was a help to the first in the procreative process. And the Holy One, blessed be He, saw that it is good that “the help” stand facing him, and that he should see and be separated from it or joined to it at his will. This is the meaning of what He said in the verse, I will make him a helper opposite him.
The meaning of the expression, it is not good, is that it cannot be said of man that “it is good” when he is alone for he will not be able to so exist. In the work of creation, “the good” means existence, as I have explained on the text, And G-d saw that it was good.³⁶²Above, 1:10.

לא טוב היות האדם לבדו, the purpose of the human species on earth will not be achieved while man who is supposed to reflect the divine image will be left to personally carry out all the menial tasks of daily life on earth by being solitary.
