2. "Give for free what has been received gratuitously," is what Jesus told His disciples. With this recommendation it is prescribed that no one be charged for something for which nothing has been paid. Now what they had received gratuitously was the faculty of healing those who were sick, and that of expelling devils, that is to say bad spirits. God gave them this faculty gratis for the alleviation of those who suffer and as a means of propagating faith. Jesus, then, recommended that they did not turn this into an object of commercialization, neither speculation, nor a means of livelihood.
