Hebrew Bible

Zechariah 14:7

5 Then you will escape through my mountain valley, for the valley of the mountains will extend to Azal. Indeed, you will flee as you fled from the earthquake in the days of King Uzziah of Judah. Then the Lord my God will come with all his holy ones with him. 6 On that day there will be no light—the sources of light in the heavens will congeal. 7 It will happen in one day—a day known to the Lord—not in the day or the night, but in the evening there will be light. 8 Moreover, on that day living waters will flow out from Jerusalem, half of them to the eastern sea and half of them to the western sea; it will happen both in summer and in winter. 9 The Lord will then be king over all the earth. In that day the Lord will be seen as one with a single name.

New Testament

Matthew 24:36

34 I tell you the truth, this generation will not pass away until all these things take place. 35 Heaven and earth will pass away, but my words will never pass away. 36But as for that day and hour no one knows it—not even the angels in heaven—except the Father alone. 37 For just like the days of Noah were, so the coming of the Son of Man will be. 38 For in those days before the flood, people were eating and drinking, marrying and giving in marriage, until the day Noah entered the ark.
