The first occurrence.
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. Gen 1:2
The primitive root.
Strong’s H7307 ruwach, a concrete noun meaning, “spirit, breath;” from Strong’s H7306 ריח ruwach, a primitive root meaning, “to smell.” The 3-letter root is resh + yud + chet.
resh ר = the head of man, thus head, first, top, beginning, man
yud י = the closed hand, thus work, throw, worship
chet ח = the wall, thus outside, divide, half
The story: The man (resh) who works (yud) outside (chet) i.e., the nomad, follows the wind, and its changes, season by season, to move his flocks to pasture. This is the root for Holy Spirit, the Ruach haKodesh. The Spirit is like a wind, and smells are carried on the wind, therefore Spirit, wind, and aroma all share the same root.
