What should a field worker do when he hears that the temple has been defiled?
When the temple is defiled, a field worker must not go back to his house to retrieve clothes or belongings. Instead, he is to leave immediately and flee to the mountains, because time is of the essence and escape from danger is the priority.
Les explains that this instruction is for working people—likely younger individuals doing common everyday tasks. Jesus says that when they hear the temple has been defiled, they should not turn back to take anything out of their house or grab their clothes. Instead, wherever they are working, they are to move out to the mountains if they want to escape. This contrasts with the wealthy, who might be tempted to retrieve expensive clothes; for the field worker, time is of the essence and escape is urgent.
