Speak against the Son of Man
In Matthew 12:31-32, this signifies to speak against the literal sense of the Word, or the divine truth as it is on earth; while to speak against the Holy Spirit is to utter blasphemies against the Divine Truth as it is in the Lord, or in heaven. (Apocalypse Explained 778[3])
Jeremiah 9:7
7
Therefore thus says Yahweh of Armies, Behold, I will melt them, and try them; for how [else] should I do, because of the daughter of my people?
