If this has been posted before, then my apologies....
Article in April ‘20 WT changes the view of the locust swarm prophecy...formerly believed to describe the worldwide preaching by Anointed. Now they say
”Simply put, these verses refer, not to our zealous preaching work, but to the activity of the Babylonian army that invaded Jerusalem in 607 B.C.E.”
They also tie in the giving of Holy Spirit to the congregation at Pentecost and thereafter.
The article is available to read in full on our least favourite website.
