On page 55 of the WT's "God's word for us through Jeremiah" book the box indicates that head archeologist of Israel's Jerusalem dig, Dr. Eilat Masar's supports the idea that Jerusalem was destroyed in 607 BCE. Its been shown through written and possible verbal interviews with the doctor that she does not support this idea at all. Today I found this video where she states at minute 3:57 that the city was destroyed in 587. This is the first visual proof that I have seen concerning this subject discussed by her.
This video is obviously a Christians propaganda piece pushing the validity of the bible showing how this Royal Bulla confirms Hezekiah's existence but ignores the obvious references to Egyptian beliefs and their god Amen-Ra.
This video clearly shows her thinking and is another nail in the WT's propaganda.
