and the stars of the sky fell to the earth, like a fig tree shedding its late [summer] figs when shaken by a strong wind.

Then the kings of the earth and the great men and the military commanders and the wealthy and the strong and everyone, [whether] slave or free, hid themselves in the caves and among the rocks of the mountains;

And the two witnesses heard a loud voice from heaven saying to them, “Come up here.” Then they ascended into heaven in the cloud, and their enemies watched them.

Then I heard a loud voice in heaven, saying,“Now the salvation, and the power, and the kingdom (dominion, reign) of our God, and the authority of His Christ have come; for the accuser of our [believing] brothers and sisters has been thrown down [at last], he who accuses them and keeps bringing charges [of sinful behavior] against them before our God day and night.
