Matthew 10:40-42

40“The person who welcomes you welcomes me, and the person who welcomes me welcomes the one who sent me.

41The person who welcomes a prophet as such will receive a prophet’s reward. The person who welcomes a godly person as such will receive a godly person’s reward.

42I can guarantee this truth: Whoever gives any of my humble followers a cup of cold water because that person is my disciple will certainly never lose his reward.”
