Ezekiel 3:17-21

3:17 Son of man, I have made thee a watchman unto the house of Israel: therefore hear the word at my mouth, and give them warning from me. 3:18 When I say unto the wicked, Thou shalt surely die; and thou givest him not warning, nor speakest to warn the wicked from his wicked way, to save his life; the same wicked [man] shall die in his iniquity; but his blood will I require at thine hand. 3:19 Yet if thou warn the wicked, and he turn not from his wickedness, nor from his wicked way, he shall die in his iniquity; but thou hast delivered thy soul. 3:20 Again, When a righteous [man] doth turn from his righteousness, and commit iniquity, and I lay a stumblingblock before him, he shall die: because thou hast not given him warning, he shall die in his sin, and his righteousness which he hath done shall not be remembered; but his blood will I require at thine hand. 3:21 Nevertheless if thou warn the righteous [man], that the righteous sin not, and he doth not sin, he shall surely live, because he is warned; also thou hast delivered thy soul.

Ezekiel 33:2-9

33:2 Son of man, speak to the children of thy people, and say unto them, When I bring the sword upon a land, if the people of the land take a man of their coasts, and set him for their watchman: 33:3 If when he seeth the sword come upon the land, he blow the trumpet, and warn the people; 33:4 Then whosoever heareth the sound of the trumpet, and taketh not warning; if the sword come, and take him away, his blood shall be upon his own head. 33:5 He heard the sound of the trumpet, and took not warning; his blood shall be upon him. But he that taketh warning shall deliver his soul. 33:6 But if the watchman see the sword come, and blow not the trumpet, and the people be not warned; if the sword come, and take [any] person from among them, he is taken away in his iniquity; but his blood will I require at the watchman’s hand. 33:7 So thou, O son of man, I have set thee a watchman unto the house of Israel; therefore thou shalt hear the word at my mouth, and warn them from me. 33:8 When I say unto the wicked, O wicked [man], thou shalt surely die; if thou dost not speak to warn the wicked from his way, that wicked [man] shall die in his iniquity; but his blood will I require at thine hand. 33:9 Nevertheless, if thou warn the wicked of his way to turn from it; if he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul.

Matthew 24:45-47

24:45 Who then is a faithful and wise servant, whom his lord hath made ruler over his household, to give them meat in due season? 24:46 Blessed [is] that servant, whom his lord when he cometh shall find so doing. 24:47 Verily I say unto you, That he shall make him ruler over all his goods.

Luke 12:36-40

12:36 And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately. 12:37 Blessed [are] those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. 12:38 And if he shall come in the second watch, or come in the third watch, and find [them] so, blessed are those servants. 12:39 And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through. 12:40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.

Acts 20:29-31

20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock. 20:30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them. 20:31 Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
