Luke 10:5-6

The Seventy were to pronounce a benediction on any household that offered them hospitality. "Peace" (Heb. shalom) was a common Jewish blessing that wished the fullness of Yahweh’s blessing on the recipient (cf. John 14:27). As the disciples ministered, it would become clear whether the host really believed their message. If he turned out to be a man of peace, namely, a man marked by the fullness of God’s blessing on his life, the disciple’s benediction would result in God’s further blessing. If the host proved unbelieving, God would not bring the fullness of His blessing on him, but the host would forfeit it (cf. Matthew 10:11-13; Mark 6:10-11).
