Mark 13:28–37 — keep watch
[28] Now from the fig tree learn her parable: when her branch is now become tender, and putteth forth its leaves, ye know that the summer is nigh; [29] even so ye also, when ye see these things coming to pass, know ye that he is nigh, even at the doors. [30] Verily I say unto you, This generation shall not pass away, until all these things be accomplished. [31] Heaven and earth shall pass away: but my words shall not pass away. [32] But of that day or that hour knoweth no one, not even the angels in heaven, neither the Son, but the Father. [33] Take ye heed, watch and pray: for ye know not when the time is. [34] It is as when a man, sojourning in another country, having left his house, and given authority to his servants, to each one his work, commanded also the porter to watch. [35] Watch therefore: for ye know not when the lord of the house cometh, whether at even, or at midnight, or at cockcrowing, or in the morning; [36] lest coming suddenly he find you sleeping. [37] And what I say unto you I say unto all, Watch.
