The subject of this fifth chapter is "The Behaviour of the Pastor towards the older and younger men and women in the congregation." Some have thought that it forms the main portion of the letter, to which all the rest is more or less introductory or supplementary. But the structure of the letter cannot easily be brought into harmony with this view. It seems to be much nearer the truth to say that the unpremeditated way in which this subject is introduced, cannot well be explained unless we assume that we are reading a genuine letter, and not a forged treatise. The connexion of the different subjects touched upon is loose and not always very obvious. Points are mentioned in the order in which they occur to the writer's mind without careful arrangement. After the personal exhortations given at the close of Chapter iv., which have a solemnity that might lead one to suppose that the Apostle was about to bring his words to a close, he makes a fresh start and treats of an entirely new subject which has occurred to him. It is not difficult to guess what has suggested the new subject. The personal exhortations with which the previous section ends contain these words, "Let no man despise thy youth; but be thou an ensample to them that believe, in word, in manner of life, in love, in faith, in purity." Timothy is not to allow the fact that he is younger than many of those over whom he is set to interfere with the proper discharge of his duties. He is to give no one a handle for charging him with want of gravity or propriety. Sobriety of conduct is to counterbalance any apparent lack of experience. But St. Paul remembers that there is another side to that. Although Timothy is to behave in such a way as never to remind his flock of his comparative youthfulness, yet he himself is always to bear in mind that he is still a young man. This is specially to be remembered in dealing with persons of either sex who are older than himself, and in his bearing towards young women. St. Paul begins with the treatment of older men and returns to this point again later on. Between these two passages about men he gives directions for Timothy's guidance respecting the women in his flock, and specially respecting widows. This subject occupies more than half the chapter and is of very great interest, as being our chief source of information respecting the treatment of widows in the early Church. Commentators are by no means unanimous in their interpretation of the details of the passage, but it is believed that the explanation which is now offered is in harmony with the original Greek, consistent with itself, and not contradicted by anything which is known from other sources. It is quite evident that more than one kind of widow is spoken of: and one of the questions which the passage raises is--How many classes of widows are indicated? We can distinguish four kinds; and it seems probable that the Apostle means to give us four kinds.
