Quote #1
[The] quiet and rural lives of the first patriarchs hath a happy something in them, which vanishes away when we come to the history of Jewish royalty. (2.3)
According to Paine, the first peoples of the world lived a happy existence until the Jewish people ruined everything by creating the tradition of having kings as rulers. In Paine's time, blaming the Jewish people for the problems of human civilization was unfortunately a common thing.
Quote #2
Government by kings was first introduced into the world by the Heathens, from whom the children of Israel copied the custom. (2.4)
Monarchy is probably the worst thing in the world as far as Thomas Paine is concerned. And he more or less blames the Jewish people, or "children of Israel" for bringing this scourge into the modern world.
Quote #3
Monarchy is ranked in scripture as one of the sins of the Jews, for which a curse in reserve is denounced against them. (2.7)
Thomas Paine is basically saying that one day, God will punish the Jewish people for bringing the scourge of monarchy into the world. Just to make things clear, he never really says where he's getting the idea that the Jewish people invented the idea of monarchy. But to say that God will one day punish them suggests that the dude is really anti-Semitic.
