"Happy are they who maintain justice, and do righteousness at all times." The meaning is that those who maintain justice are happy, teaching us that we are judged as sons; who can this come about? Precisely by giving charity at all times. Even at times when one is not doing the Almighty's will, meaning when one is transgressing, even then - doing charity attests that we are to be judged as sons… According to this, what our rabbis of blessed memory meant can now be understood: "Greatest is charity, in that it expedites the redemption", for it says, "Observe what is right and do what is just". They ask, saying that according to the verse it would seem that both are necessary – what is right, and what is just – how then did Rabbi Yehuda preach "Greatest is justice alone"? This fits well with what we have stated, that the meaning of the verse is "maintain justice". They are judged as sons; how can this be? "Do what is just" is followed by the answer: "for my salvation is near to come".
