Bede the Venerable
Catena Aurea · Markusevangelium 6
—And he went round about the villages, teaching. And he called unto him the twelve, and began to send them forth by two and two; and gave them power over unclean spirits; And commanded them that they should take nothing for their journey, save a staff only; no scrip, no bread, no money in their purse: But be shod with sandals; and not put on two coats. And he said unto them, In what place soever ye enter into an house, there abide till ye depart from that place. And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city. And they went out, and preached that men should repent. And they cast out many devils, and anointed with oil many that were sick, and healed them.
(ubi sup.) Again, allegorically; under the figure of a scrip is pointed out the burdens of this world, by bread is meant temporal delights, by money in the purse, the hiding of wisdom; because he who receives the office of a doctor, should neither be weighed down by the burden of worldly affairs, nor be made soft by carnal desires, nor hide the talent of the word committed to him under the ease of an inactive body. Itgoes on, And he said unto them, In what place soever ye enter into an house, there abide till ye depart from that place. Where He gives a general precept of constancy, that they should look to what is due to the tie of hospitality, adding, that it is inconsistent with the preaching of the kingdom of heaven to run about from house to house.
