John 1:38

Jesus turned, and saw them following. — They follow wishing, and yet not daring, to question Him. He sees this, and seeks to draw them forth by Himself asking the first question. They are not prepared for this question, and wish for more than a passing interview. They inquire, “Where dost thou sojourn?” “Where are you staying for the night?” They will visit Him and ask the many things they seek. They address Him as “Rabbi,” placing themselves in the position of His scholars; but they have not yet learnt all that John had taught them of His office. The title is natural from them, for it was the then current title of a revered teacher, and one that John’s disciples applied to him (John 3:26); but the writer remembers it was a modern word (comp. Matthew 23:7), known to Jews only since the days of Hillel (president of the Sanhedrin about B.C. 30), not likely to be known to Greeks at all, and he therefore translates it, as he does Messias and Cephas in this same section.
