YaHuWaH and Yahuwshua
When Moses asked Elohim what His name was, Elohim answered, "I am who I am" or "I will be what I will be." The name He gave Moses was YHWH (יהוה in Hebrew), what is now referred to as the tetragrammaton.
Hebrew is read from right to left, so this means "Hand, Behold, Nail, Behold", or Yodh-heh-waw-heh. The entire Bible story is enclosed within the Name of YaHuWaH! At the right Hand of YaHuWaH is Yahuwshua who was pierced by the nail and yet lives. This is the earliest known way of writing the Name of YaHuWaH.
The Hebrew people had no way of knowing how to pronounce YHWH because it was a completely new "word". The people took to swearing by the name of Ba'al. Ba'al means Lord or master. In Hosea 2:15, YaHuWaH tells them that one day they will no longer call him "my Ba'al". In Jeremiah 12:16, YaHuWaH admonishes them to call Him by His Name, not Ba'al. Then His people were sent into Babylon and the Paleo-Hebrew evolved into Modern Hebrew. This form of the Name was present almost 7000 times in the Old testament.
This form of writing YHWH is present in the Nash papyrus from the 2nd century, the Ezekiel stone from 550 BC, the Dead Sea Scrolls (150BC to 70AD), the Hosea scroll from the late 1st century BC, and the Tehillim (Psalms scroll) from 30-50 AD.
While in Babylon, YaHuWaH's people were under intense persecution, and they began to cover up the Name of God. They believed that there was an oral commandment to protect the Name of YaHuWaH. YHWH began to be pronounced as Adonai or Elohim.
We can see in the Masoretic texts from the 11th century that the vowel points had been added. The Masoretes were traditionalists with the Babylonian Talmud and were obligated to disguise the Name. Vowel points were added so the people read YHWH as Elohim. Then, when people were transliterating the bible, they didn't know that the vowel points were added at a later time, so they transliterated the name as LORD and God. This is also where the name Yahweh comes from; it's very close, but not quite, due to those vowel points.

When the yodh and the he are combined, it makes the "Yah" sound. For example, the word HalleluYAH means: to praise (Halle) you (lu) Yah (Father's name). This word has remained the same for 4000 years and is the same in 24,000 dialects of language. There are 137 names that have "Yah" in them in the Bible.
When the yodh, the heh, and the waw are combined, it makes the sound "Yahu". Yahu is on the end of 72 names in the Bible, including Eliyahu (Elijah), Yeshayahu (Isaiah), and Mattithyahu (Matthew).
When the final "heh" is added, the name becomes YaHuWaH! THIS is the name of our Elohim. YaHuWaH is very particular of His name, especially when it comes to calling Him Lord (Ba'al). In 1 Kings 18:21, we read the story of Elijah (Eliyahu) on Mount Carmel, and how he "called out" the prophets of Ba'al to prove to them that LORD was not the name of the one true YaHuWaH. Yet to this day, we still call him Lord!
In Modern Hebrew, Jesus' name is יהושע . This is pronounced "Y'shua" or "Yeshua", meaning Yahweh saves. We now know that Yahweh is actually YaHuWaH, therefore, Yahuwshua is the name of the Son! And Yahuwshua means YaHuWaH saves, or YaHuWaH is my salvation!!
All Glory, Praise, and Honor be to YaHuWah and Yahuwshua!
