"I am fearfully and wonderfully made: marvelous are thy works; and that my soul
knoweth right well. My substance was not hid from thee, when I was made in
secret, and curiously wrought in the lowest parts of the earth. Thine eyes did see
my substance, yet being incomplete; and in thy book all my members were written,
which in continuance were fashioned, when as yet there was none of them." (Ps
139:14-16)
The Hebrew word for "curiously wrought" has to do with skilled needlework, i.e.
embroidering, knitting, etc, which produce multicolored handmade articles rather
than made by machines; suggesting that the human body with all of its intricacies
was crafted by the hand of God.
The Hebrew words for "lowest parts of the earth" always, and without exception,
pertain to underground. (e.g. Ps 63:9, Isa 44:23, Ezek 26:20, Ezek 31:14, Ezek
31:16, Ezek 31:18, Ezek 32:18, and Ezek 32:24)
Some folk prefer to apply Ps 139:15 to a woman's womb; but women don't have to
go underground to get pregnant. No; I think it best, and far more sensible, to
interpret it as relating to the author's creation rather than his conception because
everyone is made, and has been made, from a Hebrew word pertaining to soil,
which contains materials derived from the disintegration of the Earth's own rocks.
Many of the Earth's rocks are, and were, formed underground and end up on or
near the surface via natural processes like volcanism, continental plate subduction,
and mighty earthquakes, etc. Once on the surface, the action of wind, water, and
temperature begin to erode rock and make dust with it.
In a nutshell: The author of Ps 139:14-16 believed that God saw his bodily
constituents while they were not yet even soil but were still underground, deep in
the Earth where they were being formed into rock which would later be broken
down to make the soil with which Adam's body was constructed per Gen 2:7
