What is the consequence of "Lo Yigra mi'Tzadik Einav"?
Rashi: He seats them with kings.
Ibn Ezra: This is like "Ein Hashem El Yere'av."
Malbim: Hashem's Hashgachah is always with a Tzadik, according to his deeds. If he increases virtue and clinging to Hashem, Hashem's Hashgachah is on all details of his actions, like one oversees his lone son for whom he has Ahavas Nefesh. However, this brings him to be tested.
What do we learn from "v'Es Melachim la'Kisei va'Yoshivem la'Netzach va'Yigbahu"?
Ibn Ezra: He puts kings on the throne. If they get haughty, He returns them from it - "v'Im Asurim ba'Zikim" (8).
Ramban: He makes kings reign. Their strength does not save them!
Malbim: If a Tzadik is lifted to sit in grandeur with kings, he will sit forever in his virtue, and always ascend.
