John 3:11

“Verily, verily, I say unto thee, we speak that we do know, etc.] Meaning either himself, and John the Baptist his forerunner, who preached the same doctrine of regeneration, internal sanctification, and evangelical repentance, as well as outward reformation, as necessary to entrance into the kingdom of heaven, or the Gospel dispensation, he declared was just at hand; or his disciples with himself, who were now with him, and whom he had called to preach the same truths he himself did; or the prophets of the Old Testament, who agreed with him in these things; or the Father that was with him, and never left him alone, and the Holy Spirit that was upon him, by whom he was anointed to preach…”

“We speak that we know, and . . . have seen--that is, by absolute knowledge and immediate vision of God, which "the only-begotten Son in the bosom of the Father" claims as exclusively His own (Joh 1:18). The "we" and "our" are here used, though Himself only is intended, in emphatic contrast, probably, with the opening words of Nicodemus, "Rabbi, we know.", &c. ye receive not, &c.--referring to the class to which Nicodemus belonged, but from which he was beginning to be separated in spirit.”

“We speak - Jesus here speaks in the plural number, including himself and those engaged with him in preaching the gospel. Nicodemus had said John 3:2, “we know that thou art,” etc., including himself and those with whom he acted. Jesus in reply said, we, who are engaged in spreading the new doctrines about which you have come to inquire, speak what we know. We do not deliver doctrines which we do not practically understand. This is a positive affirmation of Jesus, which he had a right to make about his new doctrine. he knew its truth, and those who came into his kingdom knew it also. We learn here: That the Pharisees taught doctrines which they did not practically understand. They taught much…”

“We speak what we know - I and all that believe in me. John 3:12”
