Jamieson, Fausset and Brown on Matthew 10:41

41. He that receiveth a prophet--one divinely commissioned to deliver a message from heaven. Predicting future events was no necessary part of a prophet's office, especially as the word is used in the New Testament.

in the name of a prophet--for his office's sake and love to his master. (See 2Ki 4:9 and see on 2Ki 4:10).

shall receive a prophet's reward--What an encouragement to those who are not prophets! (See Joh 3:5-8).

and he that receiveth a righteous man in the name of a righteous man--from sympathy with his character and esteem for himself as such

shall receive a righteous man's reward--for he must himself have the seed of righteousness who has any real sympathy with it and complacency in him who possesses it.
