Luke 10:1-6 TMB

1 After these things the Lord appointed seventy others also, and sent them two by two ahead of Him into every city and place whither He Himself would come.
2 Therefore He said unto them, "The harvest truly is great, but the laborers are few; pray ye therefore the Lord of the harvest, that He would send forth laborers into His harvest.
3 Go your ways; behold, I send you forth as lambs among wolves,
4 carrying neither purse, nor pack, nor shoes; and salute no man by the way.
5 And into whatsoever house ye enter, first say, `Peace be to this house.'
6 And if the son of peace be there, your peace shall rest upon it; if not, it shall return to you again.
