Matthew 10:12-13

10:12 As you enter the house, give it greetings. 10:13 And if the house is worthy, let your peace come on it, but if it is not worthy, let your peace return to you.

tn This is a metonymy; the “house” is put for those who live in it.

sn The response to these messengers determines how God’s blessing is bestowed – if the messengers are not welcomed, their blessing will return to them. Jesus shows just how important their mission is by this remark.
