Psalms 82:3

And you accept the persons of sinners: judge for the needy and the orphan, do justice to the lowly and the poor: rescue the poor and the needy, and the rest. When a case comes to you, you do not consider the cause, you do not consider the judgment, but the persons of those who have the cases. For instance, if a poor man comes having a just case, and a rich man comes having a bad case: you look at the persons, not the case. This so far according to one interpretation.

"How long will you judge unrighteously, and accept the persons of the ungodly" [Psalm 82:2]; as in another place, "How long are you heavy in heart?" Until He shall come who is the light of the heart? I have given a law, you have resisted stubbornly: I sent Prophets, you treated them unjustly, or slew them, or connived at those who did so. But if they are not worthy to be even spoken to, who slew the servants of God that were sent to them, you who were silent when these things were doing, that is, you who would imitate as if they were innocent those who then were silent, "how long will you judge unrighteously, and accept the persons of the ungodly?" If the Heir comes even now, is He to be slain? Was He not willing for your sake to become as it were a child under guardians? Did not He for your sake hunger and thirst like one in need? Did He not cry to you, "Learn of Me, for I am meek and lowly of heart"? [Matthew 11:29] Did He not "become poor, when He was rich, that by His poverty we might be made rich"? [2 Corinthians 8:9] "Give sentence," therefore, "for the fatherless and the poor man, justify the humble and needy" [Psalm 82:3]. Not them who for their own sake are rich and proud, but Him who for your sake was humble and poor, believe ye to be righteous: proclaim Him righteous. But they will envy Him, and will not at all spare Him, saying, "This is the Heir, come, let us kill Him, and the inheritance shall be ours." "Deliver," then, "the poor man, and save the needy from the hands of the ungodly" [Psalm 82:4]. […]

Defend the poor and fatherless,....

They are to be the protectors of those who lie exposed to injury and the patrons of those who want advice and assistance: Defend the poor, who have no money wherewith to make friends or fee counsel, and the fatherless, who, while they are young and unable to help themselves, have lost those who would have been the guides of their youth.

Defend the poor and fatherless. Cease to do evil, learn to do well. Look not to the interests of the wealthy whose hands proffer you bribes, but protect the rights of the needy, and especially uphold the claims of orphans whose property too often becomes a prey. Do not hunt down the peasant for gathering a few sticks, and allow the gentlemanly swindler to break through the meshes of the law. Do justice to the afflicted and needy. Even they can claim from you as judge no more than justice; your pity for their circumstances must not make you hold the scales unfairly: but if you give them no more than justice, at least be sure that you give them that to the full. Suffer not the afflicted to be further afflicted by enduring injustice, and let not the needy long stand in need of an equitable hearing.
