Matthew Henry weighs in on the Lordship Debate

Commentary on John 1:37-39

"In calling him Rabbi, they intimated that their design in coming to him was to be taught by him; rabbi signifies a master, a teaching master; the Jews called their doctors, or learned men, rabbies. The word comes from rab, multus or magnus, a rabbi, a great man, and one that, as we say, has much in him. Never was there such a rabbi as our Lord Jesus, such a great one, in whom were hid all the treasures of wisdom and knowledge. These came to Christ to be his scholars, so must all those that apply themselves to him. John had told them that he was the Lamb of God; now this Lamb is worthy to take the book and open the seals as a rabbi, Rev_5:9. And, unless we give up ourselves to be ruled and taught by him, he will not take away our sins." (emphasis mine)
