Luke 10:4

2Then he said to them, “The harvest is indeed plentiful, but the laborers are few. Pray therefore to the Lord of the harvest, that he may send out laborers into his harvest.

3Go your ways. Behold, I send you out as lambs among wolves.

4Carry no purse, nor wallet, nor sandals. Greet no one on the way.

5Into whatever house you enter, first say, ‘Peace be to this house.’

6If a son of peace is there, your peace will rest on him; but if not, it will return to you.
