Now the earth was unformed and void, and darkness was on the face of the deep. And the Spirit of God hovered over the face of the waters. Gen 1:2
The primitive root
Strong’s H6440, paniym, a concrete noun meaning, “face;” from Strong’s H6437 פנה panah, a primitive root meaning, “to turn oneself,” that is, to turn the face toward. The ancient pictographs are pey + nun + hey.
pey פ, ף = the mouth, thus open, blow, scatter, edge
nun נ, ן = the seed, thus continue, heir, son
hey ה = man with upraised arms, thus look, reveal, wonder, worship, breath
The story is to open (pey) the seed (nun), meaning the root is going down; so the face bowed down (pey + nun) in worship (hey). Dr. Benner in the Ancient Hebrew Lexicon writes of the meaning:
The face, also the presence of one through the sense of being in the face of.
Thus a man turning his face to YHVH is to seek Him or to worship Him; and YHVH turning His face to man is to cause His presence to descend to him and receive his worship.
