Mark 9:40-42

Young's Literal Translation

⁴⁰ for he who is not against us is for us;

⁴¹ for whoever may give you to drink a cup of water in my name, because ye are Christ's, verily I say to you, he may not lose his reward;

⁴² and whoever may cause to stumble one of the little ones believing in me, better is it for him if a millstone is hanged about his neck, and he hath been cast into the sea.
