Psalm of Asaph, but good for Israel is God, to the pure of heart. As it is written (Psalms 37:1), "Do not fret because of evildoers, nor be envious of the workers of iniquity." And likewise it says (Proverbs 24:20), "For there will be no prospect for the evil man; The lamp of the wicked will be put out." The Holy One, blessed be He, said: "If you see the candle of the wicked burning, do not envy them, for it is extinguished in the world to come," as it says (Proverbs 24:20), "The lamp of the wicked will be put out."
And what should one envy? The fear of the Lord all day long, in something that has a good end and does not cease forever, as it says (Psalms 23:6), "Surely goodness and mercy shall follow me all the days of my life, and I will dwell in the house of the Lord forever." Asaph said, "I was envious of the boastful, when I saw the prosperity of the wicked. Until I went into the sanctuary of God; then I understood their end" (Psalms 73:3,17).
And for whom is it good? To the pure of heart, as it says (Psalms 24:3-4), "Who may ascend into the hill of the Lord? Or who may stand in His holy place? He who has clean hands and a pure heart."
Asaph said, "I did not know that they were for their own good, and I was envious, and my feet almost stumbled" (Psalms 73:2). And why do the wicked have peace? It is because there are no constraints on their death, and they are healthy. "This woman spins wool from both picked and combed wool, and the spinning is not equal in both."
But the wicked are not like that, for there are no constraints on their death, and they are healthy. Therefore, they have peace. "What are constraints? The Holy One, blessed be He, does not delay the glory of the wicked; whatever they ask for, they are given."
Why is this similar to a sick person whom the doctor visited and took his spoon away, saying, "Give him whatever he wants to eat, for he is dying"? So Moses said to his enemies (Deuteronomy 32:41), "I will render vengeance to My enemies." Be aware that there are no constraints on their death, for they are healthy, and suffering does not touch them.
