Luke 10:6

A son of peace (uio eirhnh). A Hebraism, though some examples occur in the vernacular Koin papyri. It means one inclined to peace, describing the head of the household. Shall rest (epanapahsetai). Second future passive of epanapauw, a late double compound (epi, ana) of the common verb pauw. It shall turn to you again (ep uma anakampsei). Common verb anakamptw, to bend back, return. The peace in that case will bend back with blessing upon the one who spoke it.
