Jeru-Salem: “Fear” means a lack, which is the reason for fear. “Complete fear” is one who has no fear.
“Right” is called “whole.” “Left” is called “fear,” such as the “fear of Isaac.”
Making the middle line is both together, meaning when they unite, it becomes joined—Jeru [from the word Yiraa (fear)] Salem [from the word Shalem (complete)].
“They have eyes and do not see” is right, whole. Wherever you turn, it should be to the right, Hesed.
