Shaddai (almighty)

According  to the Torah in the book of Exodus chapter 6.  Shaddai is the name by which God was known to Abraham, Isaac, and Jacob. The name Shaddai (Hebrew: שַׁדַּי) is used as a name of God later in the book of Job.  Shaddai was translated with words meaning "Almighty".   The Talmud explains it this way, but says that "Shaddai" stands for "Mi she'Amar Dai L'olamo" - "He who said 'Enough' to His world." When God was creating the world, He completed t the process.  It is often paraphrased in English translations as "Almighty" although this is an interpretive element. The name then refers to the pre-Mosaic patriarchal understanding of deity as "God who is sufficient." God is sufficient, that is, to supply all of one's needs, and therefore by derivation "almighty".

We see in Exodus chapter 3 we are introduced to the almighty,  And Moses said unto God, Behold, when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is his name? what shall I say unto them?
 And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.
 And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, the LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations. (Exodus 3:13-15)
