The primitive root.
Strong’s H413 אל el, a primitive particle meaning, “motion, toward.” The pictographs are aleph + lamed.
aleph א = the ox head, thus strength, power, leader
lamed ל = the shepherd’s staff, thus teach, yoke, to, bind
The story: The strength of the ox (aleph) under the yoke (lamed) is applied in motion toward a goal: plowing a furrow, or turning a grindstone or mill.
