36“But nobody knows when that day or hour will come, not the heavenly angels and not the Son. Only the Father knows. 37As it was in the time of Noah, so it will be at the coming of the Human One.a38In those days before the flood, people were eating and drinking, marrying and giving in marriage, until the day Noah entered the ark. 39They didn't know what was happening until the flood came and swept them all away. The coming of the Human Oneb will be like that. 40At that time there will be two men in the field. One will be taken and the other left. 41Two women will be grinding at the mill. One will be taken and the other left. 42Therefore, stay alert! You don't know what day the Lord is coming. 43But you understand that if the head of the house knew at what time the thief would come, he would keep alert and wouldn't allow the thief to break into his house. 44Therefore, you also should be prepared, because the Human Onec will come at a time you don't know.
