Luke 10:6

New English Translation

⁶And if a peace-loving person^[a] is there, your peace will remain on him, but if not, it will return to you.^[b]

Luke 10:6 tn Grk “a son of peace,” a Hebrew idiom for a person of a certain class or kind, as specified by the following genitive construction (in this case, “of peace”). Such constructions are discussed further in L&N 9.4. Here the expression refers to someone who responds positively to the disciples’ message, like “wisdom’s child” in Luke 7:35.
Luke 10:6 sn The response to these messengers determines how God’s blessing is bestowed—if they are not welcomed with peace, their blessing will return to them. Jesus shows just how important their mission is by this remark.
