John Gill

And John answered and said, Master,.... The Syriac and Persic versions read, "our Master": we saw one casting out devils in thy name, and we forbad him; See Gill on Mar 9:38. Because he followeth not with us; the Syriac, Persic, and Ethiopic versions read, "because he followeth not thee with us"; did not join in company with them, and follow Christ along with them, and as they did.
