Household.

The basic social unit in the ancient world was the household.

Commerce and productivity were based in the family dwelling.

Workers and slaves were employed by the Master of the House.

"Peace to this house and all who dwell in it."

This was the blessing of Jesus' disciples.

When the master or mistress of a household was baptized as Christian their whole household was baptized with them.

It would seem that the Blessing of God was not just individual but extended to the whole family and even to servants and slaves.

So.....

"Peace to this house and all who dwell in it."
