Why did he say "Ra'isa"?
Rashi: You saw what the Rasha did, and You were silent.
Radak: The Rasha says that You do not see, but You saw everything.
Malbim: Surely You supervise and see the Rasha's deeds, for You see the theft and anger that Resha'im do to the poor.
Why did he say "Ki Atah..."?
Rashi: This is Your way - You see theft and anger...
Radak: Surely You see the theft and anger that Resha'im do to the poor.
Why does it say "Amal va'Cha'as Tabit"?
Malbim: You also look at his intent. Amal is his bad intent, and Cha'as is his intent to anger You.
What is the meaning of "Lases b'Yadecha"?
Rashi: With Your strength, You let Resha'im succeed in their evil.
Radak: [You see the theft] in order to be able to judge the Oni's case against the Rasha, when You will want.
Malbim: You have the ability to give to him 'payment' for his deeds.
What is the meaning of "Alecha Ya'azov Chelchah [Yasom Atah Hayisa Ozer]"?
Rashi: Yisrael Your nation, who are Your legion, they leave upon You the burden to judge the Resha'im.
Rashi citing Menachem: Ya'azov is an expression of helping, like "Azov Tazov Imo" (Shemos 23:5). Chelchah is poor, like Chelech; the Chaf is from the root.
Radak: The Oni hopes to You and leaves his case for You [to judge, for many times he sees that You help orphans]. Chelchah is like Meyachel (hope); the Hei at the end is extra.
Malbim: Do not leave his punishment to Your Shali'ach, that nature will punish him. You always help the orphan via special Hashgachah above nature, through Your legion. (The author compares Yisrael to an orphan that the king raised, and he himself gave to him his needs. The king's legions and servants will not engage in the orphan's needs, for they know that the king himself does.)
