John 1:38; John 3:2; John 3:10; John 8:4; John 11:28; John 13:13-14

38 Then Jesus turned , and saw them following , and saith unto them, What seek ye ? They said unto him, Rabbi, (which is to say , being interpreted , Master,) where dwellest thou ?
2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest , except God be with him.
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
4 They say unto him, Master, this woman was taken in adultery , in the very act.
28 And when she had so said , she went her way , and called Mary her sister secretly, saying , The Master is come , and calleth for thee.
13 Ye call me Master and Lord: and ye say well; for so I am . 14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
