Mark 13:32-37

321But of that day or hour no one knows, not even the angels in heaven, nor the Son, but the Father alone.

33“Take heed, 2keep on the alert; for you do not know when the appointed time 3will come. 344It is like a man away on a journey, who upon leaving his house and 5putting his slaves in charge, assigning to each one his task, also commanded the doorkeeper to stay on the alert. 35Therefore, 6be on the alert--for you do not know when the 7master of the house is coming, whether in the evening, at midnight, or 8when the rooster crows, or 9in the morning-- 36in case he should come suddenly and find you 10asleep. 37What I say to you I say to all, ‘11Be on the alert!’”
