Ramban

AND HE BREATHED INTO HIS NOSTRILS THE BREATH OF LIFE. This alludes to the superiority of the soul, its foundation and secret, since it mentions in connection with it the full Divine Name.. And the verse says that He breathed into his nostrils the breath of life in order to inform us that the soul did not come to man from the elements, as He intimated concerning the soul of moving things, nor was it an evolvement from the Separate Intelligences. Rather, it was the spirit of the Great G-d: out of his mouth cometh knowledge and discernment. For he who breathes into the nostrils of another person gives into him something from his own soul. It is this which Scripture says, And the breath of the Almighty giveth them understanding, since the soul is from the foundation of binah (understanding) by way of truth and faith. here signify Cabalistic concepts. See my Hebrew commentary, p. 33. This corresponds to the saying of the Rabbis in the Sifre:. “Vows are like swearing ‘by the life of the King:’ oaths are like swearing ‘by the King Himself.’ Although there is no proof for it in Scripture, there is an allusion to it: By the living G-d, and by the life of your soul.”. It does not say “by the life of G-d,” which would indicate that His life is independent of Him; rather it says, by the living G-d, thus indicating that life is His very essence. (The correctness of this translation is indicated by the patach under the word chai, which is not in the construct state, and therefore means “the living G-d.”) See my Hebrew commentary, p. 33, for further elucidation of this point. Thus there is an allusion here to the teaching of the Sifre that “an oath is like swearing ‘by the King Himself,’” since in this verse quoted, where an oath is being given, it says, by the living G-d. This is an oath “by the King Himself.” In the case of a person, however, it says “by the life of your soul,” thus indicating that in a human being his life and his soul are two independent things. This explains the tzere under the word chei, which indicates a construct state combining two independent nouns. Thus there is an allusion to “Vows are like swearing ‘by the life of the King.’” See also Note 293. And in the Midrash of Rabbi Nechunya ben Hakanah we find: “What is the meaning of the word vayinafash (and He rested)? It teaches us that the day of the Sabbath preserves all souls, for it is vayinafash” [i.e., from the word nefesh, soul]. It is from here that you will understand the expression, speaking the oath of G-d. The person learned in the mysteries of the Torah will understand. Know that those who engage in research have differed concerning man. Some say that man has three souls. One is the soul of growth, like that in a plant; or you may call this “the force of growth.” Then there is also a soul of movement in him, which Scripture mentioned concerning fish, animals, and everything that creeps upon the earth. The third is the rational soul. And there are some philosophers who say that this soul in man which comes from the Most High comprises these three forces while the soul is but one. This verse in its plain meaning so indicates for it states that G-d formed man of the dust of the ground, but he lay there lifeless like a dumb stone, and the Holy One, blessed be He, breathed into his nostrils the breath of life, and then man became a living soul, able to move about by virtue of this soul, just like the animals and the fish, concerning which He said: ‘Let the waters swarm with swarms of living creatures,’ and ‘Let the earth bring forth the living creature.’, Verse 24. This is the meaning of the expression here, ‘lenefesh chayah’ (into a living soul) man was made, meaning man turned into a soul in which there is life, after having been as a potsherd with the potsherds of the earth. For the letter lamed in the word lenefesh indicates the opposite, [namely, that from being a potsherd he became a living soul]. And so it is in the verses, And the water shall turn ‘ledam’ (into blood) upon the dry land; And it turned ‘lenachash’ (into a snake);, Verse 3. And He made the sea ‘lecharavah’ (into dry land)., 14:21. Onkelos, however, said: “And it became a speaking soul in man.” From this it would appear that his opinion coincides with those who say that man has various souls and that this rational soul which G-d breathed into his nostrils became a speaking soul. It appears to me that this also is the opinion of our Rabbis, as we may deduce from what they said: “Rava created a man. He sent him to Rabbi Zeira who spoke to him but he did not answer. Said Rabbi Zeira to him: ‘You are created by one of the colleagues; return to your dust.’” And in Midrash Vayikra Rabbah we find written: “Said Rabbi Avin: When a man sleeps, the body tells the neshamah (the moving spirit), and the neshamah tells the nefesh (the rational soul), and the nefesh tells the angel.” So also the verse, He gathers unto Himself his spirit and his breath, indicates, according to its plain meaning, that his spirit and breath are two distinct things. That being so, the verse, And the Eternal G-d formed man, states the formation of movement, that man was formed into a creature capable of movement since “formation” denotes life and perception by virtue of which he is a man and not a kneaded mass of dust, just as it is said, And the Eternal G-d formed out of the ground every beast of the field, and He brought them unto the man. And after He formed him with the power of perception, He breathed into his nostrils a living soul from the Most High, this soul being in addition to the formation mentioned, and the whole man became a living soul since by virtue of this soul he understands and speaks and does all his deeds and all other souls and their powers in man are subject to it. The letter lamed in the word lenefesh is thus the lamed indicating possession, just as in the following verses: My lord, O king, ‘lecha ani’ (I am thine), and all that I have; ‘lakoneh’ (to him that bought) it, throughout his generations; ‘lecha ani’ (I am thine), save me. Or, it may be that the verse is stating that man wholly became a living soul and was transformed into another man, as all His formations were, from now on, directed towards this soul.
