Revelation 11:7 And when they have finished their witnessing, the wild beast that ascends out of the abyss will make war with them and conquer them and kill them. 8 And their corpses will be on the broad way of the great city which is in a spiritual sense called Sod´om and Egypt, where their Lord was also impaled. 9 And those of the peoples and tribes and tongues and nations will look at their corpses for three and a half days, and they do not let their corpses be laid in a tomb. 10 And those dwelling on the earth rejoice over them and enjoy themselves, and they will send gifts to one another, because these two prophets tormented those dwelling on the earth.
The two witnesses will be killed at the end of their1, 260 days (42 months) of witnessing…when verse 10 occurs it will be the time of the following below:
1 Thessalonians 5:1Now as for the times and the seasons, brothers, YOU need nothing to be written to YOU. 2 For YOU yourselves know quite well that Jehovah’s day is coming exactly as a thief in the night. 3 Whenever it is that they are saying: “Peace and security!” then sudden destruction is to be instantly upon them just as the pang of distress upon a pregnant woman; and they will by no means escape. 4 But YOU, brothers, YOU are not in darkness, so that that day should overtake YOU as it would thieves, 5 for YOU are all sons of light and sons of day. We belong neither to night nor to darkness. 6 So, then, let us not sleep on as the rest do, but let us stay awake and keep our senses.
