Genesis 2:7 KJV And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
(The following is an anecdote from the Midrash that I find amusing. This is not scripture. Midrash is a mode of biblical interpretation prominent in the Talmudic literature. The term is also used to refer to a separate body of commentaries on Scripture that use this interpretative mode. The Talmud is the central text of Rabbinic Judaism and the primary source of Jewish religious law and Jewish theology.)
When God was about to breathe life into Adam’s body, He said: “Which place should I choose from the human body through which I will transmit life?
The mouth? No, for he will use it to speak evil of his neighbor.
The eyes? No, for he will use it to covet and be tempted.
The ears? No, for he will hear calumnies and blasphemies.
I will breathe life,” said God, “through the nostrils; for as the nostrils discern the impure and keep only the perfume, so the pious man will avoid iniquity to cling only to the words of the Torah”
(Midrash hagadol 1:74).
