The term "Jehovah" was not one that would have rolled out of the mouth of Jesus. There is no "J" sound in Hebrew/Syriac/Aramaic.
Not even in Greek for that matter--the Greek of the time.
Jehovah is a made up word to pronounce the Tetgragramaton in English The reason the name of God is a tetragramaton in the first place was to avoid making a word of it. It was not to be pronounced.
Are you aware of what the TaNakh is? It is the Hebrew text of what Christians call the Old Testament. The Christian Old Testament is not a faithful translation of the TaNakh Why? Because the translators of the Bible--the King James in particular--never opened the TaNakh, they relied upon the Greek translation called the Septaguint.
A majority of the Rabbis of tghe time were highly offended that someone would translate the TaNakh at all. The Rabbis of the time who actually spoke Greek with fluency were shocked by the inaccuracies of the translation in particular.
Deuteronomy in the TaNakh has this to say about the possibility of God being divided into three separate facets.
SHEMA YISROEL, AD-DO-NOI ELO-HAI-NOO, AH-DO-NOI ECHOD.
"Hear O Israel, G-d is our L-rd, G-d is One." (Deuteronomy 6:4)
This is the first law of Judaism, the one recitation every Jew is called upon to repeat each day.
"God i9s our Lord."
"God is One."
God is not "three".
Jesus said He came not to change the law as written by Moses, and He did not.
Why would He break this ONE law.
