John 5:33

Ye have sent unto John, and he hath borne witness unto the truth.

This has led some to suppose that the witness in the preceding verse is John the Baptist and not the Father; but the very next words of Christ reveal that this reference to John is parenthetical, introduced for possible benefit to Jesus' hearers, but not as that witness of himself needed or received in this context, because it was "from men."

Ye have sent unto John ... refers to the deputation (John 1:19) sent out by the priests and to the positive witness of Christ which was borne by the great herald (John 1:19-35; 3:23-36). The hierarchy should have believed John's witness: (1) that Jesus is the Christ; (2) that Jesus is the Messiah; (3) that Jesus is the Bridegroom; and (4) that Jesus is the Lamb of God that taketh away the sin of the world. Also John declared that "He that believeth on the Son hath eternal life; but he that obeyeth not the Son shall not see life, but the wrath of God abideth on him" (John 3:36). This passing reference to John's witness, however, is parenthetical.
