Arcana Coelestia # 5921
5921. 'That with my mouth I am speaking to you' means a revelation. This is clear from the consideration that the first thing attesting to it was the fact that they saw with their own eyes, the second that Benjamin saw with his eyes, and now the third that with his own mouth he was speaking to them. By the use of such evidence he removed all doubt that he was Joseph; he had therefore fully revealed who he was, which is why the words under explanation here imply a revelation.
Matthew 19:28
28
Jesus said to them, "Most certainly I tell you that you who have followed me, in the regeneration when the Son of Man will sit on the throne of his glory, you also will sit on twelve thrones, judging the twelve tribes of Israel.
