Matthew 10:41

He that receiveth a prophet in the name of a prophet
By "a prophet" is meant, not one that foretells things to come, but a preacher of the Gospel; for as prophesying sometimes signifies preaching, so a prophet designs a minister of the word: and to "receive" him, is not only to embrace his doctrine, but to entertain him in a kind, and generous manner; and he that does this, "in the name of a prophet", not as coming in the name of another prophet, but upon this account, and for this consideration, because he himself is a prophet; so the phrase, (Mvl) , "in the name", or on the account of anything, is often used in the Misnic writings ^F19: he that regards such a person, and shows him respect, by an hospitable entertainment of him; not because he may be related to him after the flesh; or because he may be a man of good behaviour, of a singular disposition and temper, of much learning and eloquence, of great natural parts and abilities; but because he is a faithful minister of the Gospel; he

shall receive a prophet's reward:
either a reward from the prophet himself, who shall interpret the Scriptures to him, preach the Gospel to him, lead him more fully into the truths of it, and guide him to the true, and more clear and distinct sense of the sacred writings; which is an ample reward for his kind entertainment of him: or else, that reward which God has appointed, prepared, and promised, to them who receive his prophets; and which indeed is no other, than what the prophets themselves shall receive, even the reward of the inheritance, the kingdom prepared from the foundation of the world, a reward of grace, and not of debt; since both, in their way, serve the Lord Christ.

And he that receiveth a righteous man, in the name of a righteous
man.
He that is kind and liberal to any good man, whether he is a minister of the Gospel or not, who appears to have the work of grace upon his soul, and is justified by the righteousness of Christ, and expects eternal life on that account; if he shows respect to him, purely because he has the image of Christ stamped on him, and the righteousness of Christ imputed to him, and not on any natural, worldly, or civil accounts,

he shall receive a righteous man's reward;
either from the good man himself, who will not fail to pray for his benefactor, to wish him well, and give him all the assistance he can in his Christian course; to exhort, comfort, instruct him as much, and as far as his Christian experience will furnish him with; or else the same reward of grace the righteous man himself shall have, namely, eternal life, as God's gift, through Jesus Christ our Lord.
