Wesley's Notes

4:13 The cloak - Either the toga, which belonged to him as a Roman citizen, or an upper garment, which might be needful as winter came on. Which I left at Troas with Carpus - Who was probably his host there. Especially the parchments - The books written on parchment.

Matthew Henry's Concise Commentary

4:9-13 The love of this world, is often the cause of turning back from the truths and ways of Jesus Christ. Paul was guided by Divine inspiration, yet he would have his books. As long as we live, we must still learn. The apostles did not neglect human means, in seeking the necessaries of life, or their own instruction. Let us thank the Divine goodness in having given us so many writings of wise and pious men in all ages; and let us seek that by reading them our profiting may appear to all.
