King James Bible
"Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh."
Jesus commands vigilant spiritual readiness, using a term that implies staying awake and alert like a guard on duty. This imperative concludes the parable of the ten virgins, where five were unprepared for the bridegroom's arrival. The reason for watchfulness is the complete uncertainty of timing—no human possesses knowledge of when Christ will return. This emphasizes that preparedness must be constant rather than calculated. The Son of Man, Jesus' preferred self-designation from Daniel 7:13-14, refers to his second coming in glory and judgment. This return event demands the readiness he has been urging throughout his teaching.
