This is said for the encouragement of the seventy disciples, that though they would be rejected by some, they would be received by others, who would hear them, and embrace their doctrine, as if the Messiah himself had been among them; they looking upon them as representing him: and so Christ himself considers them as ambassadors in his name, and as representing his person, taking what is done to them, as done to himself.
[Gill's Exposition of the Entire Bible]
