Mark 3:22

(ubi sup.) Now there is a great difference between those who do not understand the word of God from slowness of intellect, such as those, who are here spoken of, and those who purposely blaspheme, of whom it is added, And the Scribes which came down from Jerusalem, &c. For what they could not deny, they endeavour to pervert by a malicious interpretation, as if they were not the works of God, but of a most unclean spirit, that is, of Beelzebub, who was the God of Ekron. For 'Beel' means Baal himself, and 'zebub' a fly; the meaning of Beelzebub therefore is the man of flies, on account of the filth of the blood which was offered, from which most unclean rite, they call him prince of the devils, adding, and by the prince of the devils casteth he out devils. (ubi sup.) The Scribes also coming down from Jerusalem blaspheme. But the multitude from Jerusalem, and from other regions of Judæa, or of the Gentiles, followed the Lord, because so it was to be at the time of His Passion, that a crowd of the people of the Jews should lead Him to Jerusalem with palms and praises, and the Gentiles should desire to see Him; but the Scribes and Pharisees should plot together for His death.

And the scribes who came down from Jerusalem said, "He has Beelzebub," and, "By the prince of demons he casts out demons." It is not without reason that those who brought such blasphemy against the Lord are said to have come down from Jerusalem; but it surely foreshadowed that he would be persecuted by the citizens of that place unto death. Indeed, we read above that a great crowd from Galilee followed him, and from Jerusalem, and from Idumea and beyond the Jordan, and those around Tyre and Sidon, a great multitude, having heard what he was doing, came to him. Therefore, the crowd coming from Jerusalem followed the Lord, as also from other regions of the Jews, or even of the Gentiles. For who does not know that Idumea, Tyre, and Sidon were provinces or cities of the Gentiles? But the scribes coming down from Jerusalem persecuted him with dreadful blasphemies, because it was clearly to be in the time of his passion, that a crowd of the Jewish people would bring him to Jerusalem with palms and praises, the Gentiles would desire to see him, but the scribes and elders of the people would plot his death. Therefore, to the crowds, who seemed less instructed, always marveling at the deeds of the Lord, they endeavored to either deny these things, or to corrupt those which they could not deny with a sinister interpretation, as if these were not the works of Divinity, but of the filthiest spirit, that is Beelzebub, who was the god of Ekron. For Beel is indeed Baal, but Zebub is called a fly. Nor according to certain faulty copies is the letter k or d to be read at the end of the name, but b. Therefore Beelzebub is interpreted as Baal of the flies, that is the man of the flies, or having flies, due indeed to the filth of sacrificial blood, from whose most vile rite or name they designated the prince of demons.
