The Etymology of Jehovahby The Author on 06/13/11
There is a great deal of discussion about what the etymology of Jehovah is. However, that discussion usually focuses on Exodus 3:14 where the LORD tells Moses that "I AM That I AM" and that he should tell the children of Israel "I AM" has sent him.
"I will come to be what I will come to be" or "I will come to be as I will come to be" are two tranlations of the Hebrew I favor. Jehovah will reveal His nature to Israel (and the world) by His deeds in rescuing His people from Egypt. Jehovah became for His people everything they needed Him to be.
I also wrote about this on the the page linked to this one called "Saying Jehovah."
