Psalm 2:2 The battle against Lord’s morals and those who carry it out

יִתְיַצְּבוּ מַלְכֵי אֶרֶץ וְרוֹזְנִים נוֹסְדוּ יָחַד עַל יְהֹוָה וְעַל מְשִׁיחוֹ”

“Kings of a land stand up, and nobles take counsel together against the Lord and against His anointed?”

What is it in the Lord, that these kings and nobles are avoiding? Why are they rebelling against HaShem?

It is a struggle against G-d’s morality in the world.
Unlike Pagan worshiping, that includes a release of urges, therefor many time includes with alcohol, drags and wild sex activities,  The Lord demands Jewish Morals and Ethics, self control and restraint.  

Question: The western world is ‘cleaning itself’ from Idolatry, so is this lesson ‘not necessary’ any longer?

Answer: First, thank goodness the Torah’s ethics are spreading and affecting the world. Still, It is not only the regular form of idol worshiping that the Psalmist is talking about, it is also the consequence of it.
To elucidate: We say that the idolatry’s purpose it to allow unrestrained sex activities, the example we mentioned was of the ‘orgy’ that originally was created and performed as a way of worship in the Hellenic culture.
Two weeks ago I had an appointment with a congregant that have domestic problems, this also includes with marital relations issues. I couldn’t be more amazed about the treatment he got from his Psychologist (also a known sexologist in the area). Among other things, he suggested also ‘orgy treatment’.
I suspect, that some of today’s psychology, discourages any sort of urge’s restraint. Instead, to execute every drive and urge. – Is it a renewal of the same fake moral, just in a modern dress??

Back to the verse itself..  

Who is the ‘Anointed’ in the verse and why the wicked fight against him? Why fight him?

Well, it is a bit hard to fight the Lord, so you aim at the ambassador.

The Israelite s, as a nation are to carry the Lord’s word on earth. That is the real reason for the Judo-phobia and Antisemitism.
There always exist a reason for the hatred of G-d’s nation, but it is always a cover from the real issue, which is a struggle against the spiritual moral carried out by the Israeli nation. Moral that should be taught by the Israelites, though demands also the Morality of the entire world.
