The name Joel in Hebrew is Yo-EL.
The first part is יה (Yah) which is the short form of the most Important name, so important that the Jews do not say it. It is the name that Moses received “I am that I am.” YHWH, the Name of the Lord. Because Jews have not pronounced the name so long, scholars are no longer sure how to pronounce it. Some have come up with the name Jehovah which now we know is wrong since there was no J sound, and in very ancient Hebrew, there was no V sound.
The second part is the short form of Elohim, meaning God. EL אל. So put them together and you have יהאל
To us “The LORD is our God” does not have the impact it does in Hebrew. There may be many gods, but YHWH is our God. That is His name. As I said before, when observant Jews want to say his name outloud, such as in the blessing, Barukh HaShem. They literally say, “Bless the-Name.”
The LORD’s name was considered so holy to the Jews that any book of scriptures that was falling apart and getting old had its own burial room in the temple. This is where archeologists have found some scriptures.
The opposite of Yo-el’s name is Elijah. Elijah means God is LORD.
The KJV uses all capitals LORD when refering to YWHY or יחוה
