Matthew 24:40-44 (New International Version)

⁴⁰Two men will be in the field; one will be taken and the other left. ⁴¹Two women will be grinding with a hand mill; one will be taken and the other left.

 ⁴²"Therefore keep watch, because you do not know on what day your Lord will come. ⁴³But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. ⁴⁴So you also must be ready, because the Son of Man will come at an hour when you do not expect him.
