And shall begin to smite his fellowservants, and to eat and drink with the drunken;

People's New Testament

24:49 And shall begin to beat his fellow-servants. There is no sin more common among those who are clothed with authority than oppression. There have been no worse oppressors than priests.

And to eat and drink with the drunken. What first disgusted Luther with the faith in which he had been reared was the profligacy of the priests and monks. It has often been the case that the Vatican was the very hot-bed of scandal.

Matthew Henry's Concise Commentary

24:42-51 To watch for Christ's coming, is to maintain that temper of mind which we would be willing that our Lord should find us in. We know we have but a little time to live, we cannot know that we have a long time to live; much less do we know the time fixed for the judgment. Our Lord's coming will be happy to those that shall be found ready, but very dreadful to those that are not. If a man, professing to be the servant of Christ, be an unbeliever, covetous, ambitious, or a lover of pleasure, he will be cut off. Those who choose the world for their portion in this life, will have hell for their portion in the other life. May our Lord, when he cometh, pronounce us blessed, and present us to the Father, washed in his blood, purified by his Spirit, and fit to be partakers of the inheritance of the saints in light.
