Re 11:7  And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and KILL them.

SUMMARY: Apparently, God is concerned with those who KILL His prophets by shedding BLOOD. And it looks like Jerusalem (now unsaved church, Babylon) was the first to shed blood: both literally but more so spiritually in tribulation as they seek to silence the voice of the Elect with false gospels.
