Mark 13:31-37

31 Heaven and earth shall pass away: but my word shall not pass away.

32 But of that day or hour no man knoweth, neither the angels in heaven, nor the Son, but the Father.

33 Take ye heed, watch and pray. For ye know not when the time is.

34 Even as a man who, going into a far country, left his house and gave authority to his servants over every work and commanded the porter to watch.

35 Watch ye therefore (for you know not when the lord of the house cometh, at even, or at midnight, or at the cock crowing, or in the morning):

36 Lest coming on a sudden, he find you sleeping.

37 And what I say to you, I say to all: Watch.
