When was that scripture applied to the Jews ? ,hundreds of years before Jesus or Christianity ever came upon the scene.
Did the Jews ever identify themselves as Jehovah`s Witnesses from that time on ? No .And Jesus never condemned them for not taking up that name upon themselves.
In fact the name / word "Jehovah" never existed before the 13th century when it was invented by a Spanish Catholic Monk no less, taking the latinized four consonants of the Hebrew Tetragrammaton as JHVH and adding some vowels ,coming up with Jehovah .
Now think about what the Bible actually says and not what Jehovah`s Witnesses say .
Phillipians 2:10 So that in the name of Jesus every knee should bend of those in heaven and those on earth and those under the ground and every tongue should openly acknowledge that Jesus Christ is lord to the glory of God the father
And finally :.Acts 11:26 b "it was first in Antioch that the disciples were by divine providence called Christians "
Think about that phrase " by divine providence " doesnt that mean by GOD / JEHOVAH / YAHWEH, the ALMIGHTY himself ?
