Psalm 5:5 G-d hate the wickedness

“כִּי לֹא אֵל חָפֵץ רֶשַׁע אָתָּה לֹא יְגֻרְךָ רָע”

“For You are not a God Who desires wickedness; evil does not abide with You”

The consistent question of the existent and so often also the dominion of evil in the world, is the source of this verse.

Yes, the evil exist and might prosper. But You – G-d hate the wickedness, the Evil does not abide with You.

Psalm 2:7 An educational answer: ‘My firstborn Israel’.

“אֲסַפְּרָה אֶל חֹק יְהֹוָה אָמַר אֵלַי בְּנִי אַתָּה אֲנִי הַיּוֹם יְלִדְתִּיךָ”

“I will tell of the decree; The Lord said to me, “You are My son; this day have I begotten you.

Did anyone asked a prince: ‘Do you want to be one?’, is it up to him to accept the responsibilities this role brings along with it?
It seems that ‘free will’, is not exactly whatever you want to do or to be. Why are the Israelites are those who carry the Lord’s word on earth – because He said so, a decree!
King David sends us back to the Bible, the first time it appears is in the book of Exodus (4:22): “So said the Lord, “My firstborn son is Israel.”.

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?

Psalm 2:1 Wicked attacks against Israel are vain

The second chapter of Psalms continues the first. While Psalm 1 is a private question and wonder about the prosperity of the wicked, Psalm 2 raises the same question, this time ‘on the large scale’ about the prosperity of evil nation and wicked forces in the world.

“לָמָּה רָגְשׁוּ גוֹיִם וּלְאֻמִּים יֶהְגּוּ רִיק”

“Why have nations gathered and kingdoms think vain things?

The Hebrew word the Psalmist uses for ‘gathered’ is not the common one. We would usually say:
“למה נאספו גויים” ,
the term “Ragshu” (רגשו) as appears in our verse means excitement, more like a fuss. Each time there is a different force or nation that wants to diminish the Israeli nation.

Psalm 1:4 The wicked as a detached husk

“לֹא כֵן הָרְשָׁעִים כִּי אִם כַּמֹּץ אֲשֶׁר תִּדְּפֶנּוּ רוּחַ”

“Not so the wicked, but [they are] like chaff that the wind drives away.

(The allegory continues) Unlike the righteous persons that are described as a solid tree close to it’s source of water,
The wicked is detached and unstable, like a chaff.  Chaff, is the waste of the fruit. While it is attached to the fruit and the seed it has value, once detached, the chaff is worthless, gone with the wind.
