Mark 9:39-41

Amplified Bible

³⁹ But Jesus said, “Do not stop him; for there is no one who will perform a miracle in My name, and be able soon afterward to speak evil of Me. ⁴⁰ For he who is not against us is for us.^{(A) 41} For whoever gives you a cup of water to drink because of your name as followers of Christ, I assure you and most solemnly say to you, he will not lose his reward.
