Or, the Lord did not wish the disciples to possess and carry with them these things, not that they were not necessary to the support of this life, but because He sent them thus to shew that these things were due to them from those believers to whom they announced the Gospel, that so they might neither possess security, nor carry about with them the necessaries of this life, either great or little. He has therefore, according to Mark, excluded all except a staff, shewing that the faithful owe every thing to their ministers who require no superfluities. But this permission of the staff He has mentioned by name, when He says, They should take nothing in the way, but a staff only.
