Jesus ensured that though His people will be in the world during the hour of trial that will come upon all the world, they will be kept during the hour of trial:
John 17
6 "I have revealed Your name to the men whom You gave to Me out of the world. They were Yours, and You gave them to Me, and they have kept [τηρησω tēréō: guarded from loss or injury by keeping their eye upon and preserving] Your word."
11-15: "And now I am in the world no longer, but these are in the world, and I come to You, Holy Father. Keep [tēréō] them in Your name, those whom You have given Me, so that they may be one as We are.
While I was with them in the world, I kept [tēréō] them in Your name. Those that You have given Me I have kept [tēréō], and none of them is lost, except the son of perdition, that the Scripture might be fulfilled.
And now I come to You, and these things I speak in the world that they might have My joy fulfilled in them.
I have given them Your Word, and the world has hated them because they are not of the world, even as I am not of the world.
I do not pray for You to take them out of the world, but for You to keep [tēréō] them from the evil."
During the hour of temptation that is going to come upon all the world to test them that dwell upon the earth (Revelation 3:7-13), the harlot, Babylon the Great will be destroyed in one hour (Revelation 18:10, 17, 19) by ten kings, who will be reigning for one hour with the beast (Revelation 17:12-13), who will be given authority to continue for 42 months (Revelation 13:5), and will make war against the saints and overcome them (Revelation 13:7).
The hour of trial is not two hours (42 months + 42 months or seven years), but one hour (42 months).
Luke 21:17-19: "And you shall be hated by all for My name's sake. But there shall not a hair of your head perish. By your patience [ὑπομονή hypomonḗ: hopeful, believing endurance] you will gain your souls."
Revelation 2:10: "Do not at all fear what you are about to suffer. Behold, the Devil will cast some of you into prison, so that you may be tried. And you will have tribulation ten days. Be faithful to death, and I will give you the crown of life."
Luke 21:34-36
"And take heed to yourselves, lest your hearts are weighed down with headaches and drinking and anxieties of this life;
and that day should suddenly come on you; for it shall come as a snare on all those sitting on the face of the whole earth. Watch therefore, praying in every season that you may be counted worthy to escape all these things which shall occur, and to stand before the Son of man."
