There are so many countless passages in scripture regarding the end times. I quote Daniel here, but Matthew 24 has the greek phrases commonly derived end times to be called escatology from the greek word eskatos!
Daniel 12:
וְאַתָּה דָֽנִיֵּאל סְתֹם הַדְּבָרִים וַחֲתֹם הַסֵּפֶר עַד־עֵת קֵץ יְשֹׁטְטוּ רַבִּים וְתִרְבֶּה הַדָּֽעַת׃
But thou, O Daniel, shut up the words, and seal the book, [even] to the time of the end: many shall run to and fro, and knowledge shall be increased.
Shalom Alecheim!
