I’m not sure where you got this idea, but it isn’t correct...even the Didache, predating even the Bible as we know it today, says
Didache (100 A.D.)
Watch for your life's sake. Let not your lamps be quenched, nor your loins be unloosed, but be ye ready, for ye know not the hour in which our Lord cometh. But as often as you come together, seeking the things that are befitting to your souls: for that whole time of your faith will not profit you, if you are not made perfect in the last time. For in the last days false prophets and corrupters shall be multiplied, and the sheep turned into wolves, and love will be turned to hate; when the lawlessness increases, they shall hate and betray one another, and then shall appear the world deceiver as Son of God, and shall do signs and wonders and the world shall be delivered into his hands, and he shall do iniquitous things which have never yet come to pass since the beginning. Then the creation of men shall come into the fire of trial, and many shall be made to stumble and perish; but they that endure in the faith shall be saved from under the curse itself. And then shall appear the signs of truth; first, the sign of the outspreading in heaven; then the sign of the sound of the trumpet; and the third, the resurrection from the dead; yet not all, but as it is said: The Lord is coming and all his saints with Him, then the world will see the Lord coming upon the clouds of heaven."
