In the New Testament being a witness of Jesus is mentioned over 20 times....... being a witness of Jehovah is not mentioned at all. And only once in the Old Testament.
Besides which their was no J in the Jewish alphabet up to 400 plus years ago.
Sorry guys but Jehovah and Jesus were not their proper names after the Latin alphabet took over. Getting Latinized is a bitch.
The name of God used most often in the Hebrew Bible is YHWH ( י ה ו ה), also known as the Tetragrammaton (Greek for "four-letter [word]"). Hebrew is an abjad, so the word's letters Yōd, Hē, Vav, Hē are usually taken for consonants and expanded to Yahweh in English.
Jesus' name in Hebrew was “Yeshua” which translates to English as Joshua.
To this day we are not even close to understanding God and Jesus's names.
Your prayers or messages aren't answered if you can't call the person you worship by their proper name. They don't pick up the phone.
It was Rutherford ( a drunk) who decided to use the name Jehovah as in Jehovah's Witnesses. By doing that he did not get the singular message out that being a witness for Jesus would have been. People could understand a witness for Jesus.......but Jehovah? To this day.......not really.
