These Two Witnesses are going to prophecy for 3 1/2 years and during that time they will be safe from death.
If anyone tries to hurt them, fire will proceed out of their mouths and devour the enemy.
When they have finished their testimony, they will be overcome by the Beast/Antichrist, who will make war against them and will kill them and their bodies will lay in the street of Jerusalem, which is spiritually called Sodom and Egypt at that time, because those living there will resemble those of Sodom in the days of Lot and the conduct of Israel in Egypt for those 3 1/2 days and the people of all nationalities will not want their bodies to be buried but they will rejoice over them; even giving gifts to one another because the two witnesses who had tormented them by their testimony and plagues are dead.
