Matthew 10:40-42
40 “Whoever receives you receives me, and whoever receives me receives him who sent me. 41 The one who receives a prophet because he is a prophet will receive a prophet’s reward, and the one who receives a righteous person because he is a righteous person will receive a righteous person’s reward. 42 And whoever gives one of these little ones even a cup of cold water because he is a disciple, truly, I say to you, he will by no means lose his reward.”
