Matthew 10:40-42

40“Anyone who receives you receives me, and anyone who receives me receives the Father who sent me.

41If you receive a prophet as one who speaks for God, you will be given the same reward as a prophet. And if you receive righteous people because of their righteousness, you will be given a reward like theirs.

42And if you give even a cup of cold water to one of the least of my followers, you will surely be rewarded.”
