'In My Name' in the Bible

and said unto them, "Whosoever receiveth this child in my name, receiveth me. And whosoever receiveth me, receiveth him that sent me. For he that is least among you all, the same shall be great."

And he said, "Take heed, that ye be not deceived. For many will come in my name, saying of themselves, 'I am he.' And the time draweth near. Follow ye not them, therefore.
