Meta. Jethro means his excellence, his superiority, his abundance. Midian means judgment, and Horeb, solitude.The metaphysical interpretation of Exod. 3:1 is that we have to go into the solitude of the inner and lead our flock of thoughts to the back of the wilderness, where dwells the exalted One, the divine I AM, whose kingdom is good judgment. There we are in training forty years, or until we arrive at a four-sided or balanced state of mind.
