John Gill

Brethren, pray for us. Which is added with great beauty and propriety, after the apostle had so earnestly and affectionately prayed for them; and this is directed, not to the pastors of the church only, but to all the members of it, whom the apostle styles "brethren" in a spiritual relation, as he often does; and of whom he requests, that they would pray for him, and the rest of his fellow ministers and labourers in the word, that God would more and more qualify and fit them for their work, assist in private studies and meditations, give them freedom of thought, liberty of expression, and a door of utterance, and follow their ministrations with a divine blessing and success, and deliver them out of the hands of unreasonable men; See Gill on Heb 13:18. . 1 Thessalonians 5:26 th1 5:26 th1 5:26 th1 5:26Greet all the brethren with an holy kiss. In opposition, to an unchaste and hypocritical one. His meaning is, that they would salute the members of the church in his name, and give his Christian love and affections to them. And his view is to recommend to them brotherly love to each other, and to stir them up to the mutual exercise of it more and more.
