In terms of spiritual mechanics/dynamics, what happens when a person is born?

[tonychanyt]

English Revised Version, Genesis 2:7 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 breath
נִשְׁמַ֣ת (niš·maṯ)
Strong's 5397: A puff, wind, angry, vital breath, divine inspiration, intellect, an animal

Strong's Hebrew: 5397. נְשָׁמָה (neshamah) — 23 Occurrences

Brown-Driver-Briggs

1. breath of God as hot wind kindling a flame
2. breath of man
3. every breathing thing
4. spirit of man

soul
לְנֶ֥פֶשׁ (lə·ne·p̄eš)
Strong's 5315: A soul, living being, life, self, person, desire, passion, appetite, emotion

Step 1: A physical body is formed.
Step 2: A detached breath/spirit from God enters the body, a breath breathed out from God.
Step 3: The person's self/soul is generated.

I think these steps are true for everyone.

Elsewhere, ESV Job 27:

3 as long as my breath [H5397] is in me,
and the spirit [H7307] of God is in my nostrils,
4 my lips will not speak falsehood, and my tongue will not utter deceit.

Strong's Hebrew: 7307. ר֫וּחַ (ruach) — 377 Occurrences

The meanings of H5397 and H7307 overlap. Brown-Driver-Briggs:

1. breath of mouth or nostril
2. wind
3. spirit, as that which breathes quickly in animation or agitation = temper, disposition
4. spirit of the living, breathing being
5. spirit as seat of emotion
6. occasionally, (and late) = seat or organ of mental acts
7. rarely of the will
8. especially of moral character
9. spirit of God (94 times)

Berean Standard Bible:

as long as my breath is still within me and the breath of God remains in my nostrils.

The (detached) breath [H5397] of life is related to the (undetached) Spirit [H7307] of God.
