이사야 48:17의 Musar

Wherefore the excellence of good-will is related to life, being a source of superiority and a fount of good fortune according to the saying (id., xvi. 15), "In the light of the king's countenance is life; and his favor is as a cloud of the latter rain." So also in that of man; thus Pharaoh bore good-will to Joseph, even bringing him unto kingly power. Thus Ahasuerus, too, bore good-will to Mordecai. Thou seest how such a man is treated and exalted; how much more he to whom God bears good-will, therefore the saying (Isa. xlviii. 17), "I am the Lord thy God which teacheth thee to profit, which leadeth thee by the way that thou shouldst go." The sage said, "Whosoever is contented is rich: whosoever is obedient is joyous: whosoever is rebellious is sad." He was wont to say, "He who is not content of his own accord with his condition will be (compelled to be) satisfied despite himself."
