The primitive root.
Strong’s H1980 הלך halak, a primitive root meaning, “to walk.” The 3-letter root is hey + lamed + kaph.
hey ה = man w/ raised arms, thus look, reveal, wonder, worship, breath
lamed ל = the shepherd’s staff, thus teach, yoke, to, bind
kaph כ, ך = the open palm, thus bend, open, allow, tame
The lamed + kaph pair often pictures the staff (lamed) in the palm (kaph), as a nomad would grasp when he went anywhere, thus “to walk.”
Our English word “walk” is from this Hebrew pair: see the l – k, the lamed + kaph? Hebrew is the mother tongue, from which all the languages were divided at Babel.
The story: The path revealed (hey) is the path to walk (lamed + kaph), i.e., walking not in the way of the world, but in God’s way which He has revealed.
