The Coming of the Son of Man
29 But immediately after the oppression of those days, the sun will be darkened, the moon will not give its light, the stars will fall from the sky, and the powers of the heavens will be shaken;  30 and then the sign of the Son of Man will appear in the sky. Then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of the sky with power and great glory. 31 He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.
32 “Now from the fig tree learn this parable. When its branch has now become tender, and puts forth its leaves, you know that the summer is near. 33 Even so you also, when you see all these things, know that it is near, even at the doors. 34 Most certainly I tell you, this generation  will not pass away, until all these things are accomplished. 35 Heaven and earth will pass away, but my words will not pass away.
No Man Knoweth the Day and Hour
36 But no one knows of that day and hour, not even the angels of heaven, but my Father only. 37 “As the days of Noah were, so will be the coming of the Son of Man. 38 For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ship, 39 and they didn’t know until the flood came, and took them all away, so will be the coming of the Son of Man. 40 Then two men will be in the field: one will be taken and one will be left; 41 two women grinding at the mill, one will be taken and one will be left. 42 Watch therefore, for you don’t know in what hour your Lord comes. 43 But know this, that if the master of the house had known in what watch of the night the thief was coming, he would have watched, and would not have allowed his house to be broken into. 44 Therefore also be ready, for in an hour that you don’t expect, the Son of Man will come.
The Unfaithful Servant
45 “Who then is the faithful and wise servant, whom his lord has set over his household, to give them their food in due season? 46 Blessed is that servant whom his lord finds doing so when he comes. 47 Most certainly I tell you that he will set him over all that he has. 48 But if that evil servant should say in his heart, ‘My lord is delaying his coming,’ 49 and begins to beat his fellow servants, and eat and drink with the drunkards, 50 the lord of that servant will come in a day when he doesn’t expect it, and in an hour when he doesn’t know it, 51 and will cut him in pieces, and appoint his portion with the hypocrites. There is where the weeping and grinding of teeth will be.
