Musar su Malachia 3:13

There is another way to intelligently understand how jealousy and lust are very ruinous qualities, and in this vein Solomon said : "Let not thy heart envy sinners, but be in the fear of the Lord all the day" (Prov. 23:17). When a man envies sinners seeing their wealth and prosperity and sees righteous men growing poorer and being sore afflicted, and, from all of this, his soul rejects reverence for God and His judgements, and rejects those who study the Torah and fulfill it, as it is said : "Your words have been all too strong against Me, saith the Lord. Ye have said : 'It is vain to serve God; and what profit is it that we have kept His charge, and that we have walked mournfully because of the Lord of Hosts? And how we call the proud happy, yea, they that work wickedness art built up; yea, they try God and are delivered" (Malachi 3:13-15).
