Carry neither purse, nor bag, nor shoes: and greet no man by the way.
All Commentaries on Luke 10:4 Go To Luke 10
Ambrose of Milan
AD 397
Consider it is not only “Salute no man,” but “by the way” is not carelessly added. When Elisha sent his servant to lay his staff on the body of the dead child, he also commanded him not to salute any man he met. He ordered him to hurry to go in order to perform the office of proclaiming the resurrection, lest he be turned from the duty laid upon him by conversation with someone along the way. The zeal of greeting is not taken away here, but an obstacle to the practice of piety is removed. When divine commands are given, human obligations are surrendered for a little while. Salutation is fine, but the performance of duties to God is finer because it is more fitting. Hindrance of these duties has often brought offenses. Even honorable acts are prohibited, for fear that the grace of ceremony deceive and hinder the ministry of the task, delay in which is sinful.
