Interesting OP!
When the news about that bulla broke, several Witnesses shared that news item on Facebook.
All comments were "you see, Bible is true and correct!"
Until someone noticed the winged suns and Tammuz / phallic symbol.
Then most comments were "Yeah right, as if that belonged to Hezekiah"
Well waddayathink.....some other king Hezekiah son of Ahaz lived in the palace on mount Ofel at the same time, and threw his bulla out?
They don't recognise truth if it slaps them in the face :-(
(And yes, most of us were the same before we woke up)
