They were not to take money, clothes, or shoes.
Jesus wanted them to depend on Him. He told
them that the "workman was worthy of his meat."

They were going to bless people by healing them,
give them the good news of the kingdom, so they
were worthy to receive those things which were
necessary.

They were not beggars, those who took them in
would be blessed and rewarded. They were not
to move around but find out who in that city
was worthy to take them in.

They were to bless the house where they stayed,
if they were not received well, they were to leave
shaking the dust from their feet as a witness
against it.
Read Matthew 10:9-14
