“I Am Who I Am” was God’s answer to Moses when he asked about what to call Him. In the footnotes in my NIV it says that, “Lord (Yahweh) sounds like and may be derived from the Hebrew for I Am (Exodus 3:14). Then in verse 15 He says that He is the God of Abraham, Isaac and Jacob (why not Israel) and then says that is how He wants to be remembered. “God” here is Elohim. Now I do want to say that it depends on your concordance as to exactly how some of these names are listed; my Strong’s is slightly different than my NIV Concordance.
A generic name for god is “el.” So if you are reading and a name has “el” in it like Israel or Bethel you know it has something to do with a god or God. According to the Vine’s Dictionary in the ancient world it was thought that if you knew a deity’s name that would give you a special “in” with that deity. Nice to know that humanity has not changed much some people still think that they can manipulate God.
The verse that actually started this study was Exodus 6: 2+3. Moses is “pointing out” all of the trouble that the Children are having but God sees it as the opportunity He needs for their deliverance. In the verse He says that Abraham, Isaac and Jacob knew Me as God Almighty (El-Shaddai) but they did not know Me as Lord (Yahweh). Vine’s talks about how scholars relate this phrase (El-Shaddai) to the power of mountains. In Psalm 80 they also had a “God Almighty” but there it is Elohim Saba. So you may need to look for exactly which phrase it is that is being used and I can tell you that the translation you read may handle these phrases just a little different.
In researching I found this website which maybe helpful to you: http://www.hebrew4christians.com/Names_of_G-d/El/el.html
So what name do you know God as or what name has He made Himself known to you?
