אל שדי. שם התואר וטעמו תקיף וכן "כקול שדי" (יחז' א כד)...ורבים פירשוהו מגזרת שודד שהוא מנצח ומתגבר, וטעם להזכיר השם הזה בפרשה הזאת לירא אברם וימול, והנכון כי השם הנכבד והנורא נקרא כנגדו וזה שם התואר כנגד המעשה, כי העולם עומד על אלה שני השמות, והמבין סוד השם יאמין:
GOD ALMIGHTY. Shaddai is an adjective meaning mighty. Shaddai in like a mighty voice (ke-kol shaddai) (Ezek. 1:24) is similar... Many derive Shaddai from the same root as shoded (overpowering), meaning, He is victorious and overpowering. The reason God used this name at this time was to impress upon Abraham the fear of God so that he would circumcise himself. The correct interpretation of the divine names is as follows: Shaddai is an adjective describing God’s power over creation. The Tetragrammaton (*Micah here- God's most holy name- יהוה), God’s revered and awesome name, stands in contrast to it. The world exists by virtue of these two names. Whoever understands the secret of God’s name will accept my interpretation.
