EL-SHADDAI : Hebrew meaning God Almighty. The word is Archaic, but there is no doubt that it means “strong so as to overpower.” Paul brings out the meaning of the revelation when he glorifies the faith which it kindled anew in Abram, ‘being fully assured that, what He had promised, He was able also to perform’ {Romans 4:21}.
El Shaddai can be translated as ” God the Mountain One”. This conveys a word picture of God as a mountain of strength and His presence as a majestic shelter and shade. The word “Shaddai” comes from the Hebrew root word shad, meaning “breast”. It gives us a powerful picture of God as “the One who nourishes, supplies, and satisfies.” (scripturalgrace,com)
“The Lord,” the Author of existence and performance. “God Almighty,” El Shaddai. “El,” the Lasting, Eternal, Absolute. “Shaddai,” the Irresistible, Unchangeable. (Barne’s Notes)
