The first occurrence.
I sought YHVH, and He heard me, and delivered me from all my fears. Psa 34:4
The primitive root.
Strong’s H4035 meguwrah, a concrete noun meaning, “what is feared,” also a granary, a barn, i.e., stored up against the fear of want. From Strong’s H4032, magor, a concrete noun meaning, “fear, dread;” from Strong’s H1481 גור guwr, a primitive root meaning, “to sojourn, to turn aside from the way.” The 3-letter root is gimel + vav + resh.
gimel ג = the foot, thus foot, walk, gather
vav ו = the tent peg, thus add, secure, hook
resh ר = the head of man, thus head, first, top, beginning, man
The story: The partial pair is gimel + resh, the walking (gimel) man (resh) or nomad, sojourner, traveler. In his heart however, is a secure tent peg (vav), a place to cease from wandering. He is always looking for it. The concept of fear comes from the understanding that when one is afraid of someone or something, he turns aside from him or it to avoid it.
