Matthew 10:40-42

40 "He who receives you receives Me, and he who receives Me receives Him who sent Me.

41 He who receives a prophet in the name of a prophet shall receive a prophet's reward. And he who receives a righteous man in the name of a righteous man shall receive a righteous man's reward.

42 And whoever gives one of these little ones only a cup of cold water in the name of a disciple, assuredly, I say to you, he shall by no means lose his reward."
