It is written in the Tikunei Zohar: “‘I am the L-rd, I do not change’ (Malachi 3:6). But for the iniquitous, He does change.”⁴ 26, p. 71b. He hides Himself in many garments and concealments. Yet, if a person knows that the Holy One is hidden there, it ceases to be concealment, for “all the workers of iniquity will be dispersed” (Psalms 92:10). And this is the meaning of: “I will hide my face from them.” That is, He will hide from them in a way that they do not realize He is hidden there. Similarly, I heard from my Teacher (the Baal Shem Tov) that the words: “The enemy said, I will pursue, I will overtake, I will divide [the spoil]” (Exodus 15:9), all begin with the letter aleph. Because the Alupho shel Olam (the Master of the World) is hidden there, in the mystery of the Name “Sa’el” (סאל). Toldos Yaakov Yosef, Bereishis; Ben Poras Yosef, p. 111a
