Will they say Jehovah or Jesus or both?
Ask many witnesses and see if you get a different answer.
In the bible Jesus is called Savior as well as Jehovah.
So is it savior or saviors?
The Watchtower refers to Jesus as Savior her e below and sometimes they say that Jehovah is the only savior...
"It is clear from this that our Saviour was born before the 25th of December . . . At that time it is cold, and especially in the high and mountainous regions about Bethlehem. God has concealed the time of [Jesus'] birth. . . . Nor was it of consequence to know the time; if it had been, God would have preserved the record of it."
