Theophylact of Ohrid — on 2Tim 4:13 (Commentary on 2 Timothy)

“Here the apostle speaks of the cloak; he asks for it so as not to have need to take from others. For everywhere he takes great care not to be in need of others. Some, however, think that this is a case, a container in which the books were kept. Why did he need books when he was preparing to depart to God? So that he might pass them on to the faithful, that they might have them in his stead. Probably, they contained within themselves something more valuable.”
