YHVH (JHVH) - the Tetragrammaton - is always rendered in the King James Bible as LORD (all capitals, the 'L' one size larger). When reading Scripture (the Torah and Tanach) in services, the Tetragrammaton was pronounced as Adonai - Lord, since the secret 4 letter name was only pronounced once a year in the Holy of Holies at Yom Kippur - the Day of Atonement.
In the KJV, when the word 'Adonai' appears in the Hebrew text, it is always rendered 'Lord' - with only the 'L' capitalized. When the KJV reads 'lord' (all small letters), the Hebrew is ba'al, such as 'lord of the house.' Obviously it also duplicates the pagan god, Ba'al or ba'al.
As far as I know, when the King James scholars considered pronouncing the Tetragrammaton, they took the vowels from 'Adonai' and inserted them between the 4 consonants of the Tetragrammaton - somewhat roughly rendering the pronunciation 'Jehovah' - considering that the Hebrew 'vowels' were always a bit fluid. When the Tetragrammaton is rendered in the Masoretic text, with the vowel 'pointings' written underneath the four consonants, the pronunciation is still 'Jehovah' - given the 'J' instead of 'Y'. When the Tetragrammaton is rendered beginning with 'Y', the common fluid vowel assumptions apply - Yahweh, Yaveh.'
In common everyday speech the whole stew above is ignored and the Tetragrammaton is referred to as 'the Name' haShem or Ha-Shem. Of course 'Shem' is the name of one of Noah's sons, the patriarch of the line of Messiah - Jesus. Some ancient rabbinical scholars considered Noah's son Shem as Melchizedek - the King of Righteousness, also the king of what became Jerusalem.
Interesting take of a possible connection between Melchizedek and Noah’s son, Shem. I checked the genealogy and counted 10 generations between Shem and Abram/Abraham, so it is possible.
From Luke Chapter 3 ...
Abraham, the son of Terah,
the son of Nahor,
the son of Serug,
the son of Reu,
the son of Peleg,
the son of Eber,
the son of Shelah,
the son of Cainan,
the son of Arphaxad,
the son of Shem,
the son of Noah
Genesis 11 says ...
These are the generations of Shem. When Shem was 100 years old, he fathered Arpachshad two years after the flood. 11 And Shem lived after he fathered Arpachshad 500 years and had other sons and daughters.
So Shem lived to be 600 years old. Is that long enough tp survive 10 generations? Hmm!
