Musar su I Re 21:27

The eighth principle is submission in [his] actions - such that one should be accustomed to [giving] a gentle response, as it is stated (Proverbs 15:1), "A gentle response allays wrath." For this is the way of lowliness, as it is stated (Isaiah 29:4), "And you shall speak from lower than the ground, your speech shall be humbler than the sod" - the opposite of that which is stated about a rich man who is proud: "The rich man’s answer is harsh" (Proverbs 18:23). And he should not be occupied with the beauty of clothing and jewelry, as it is stated (Exodus 33:5), "and now take off your finery." And it is stated about Ahab, (I Kings 21:27), "he fasted and lay in sackcloth and walked about subdued." And God, may He be blessed, said about this (I Kings 21:29), "Have you seen how Ahab has submitted?" And the matter of "walked about subdued," is the opposite of the way of kings, who walk with many soldiers and the din of a troop. And he should always lower his eyes, like the matter that is stated, (Job 22:29), "for He saves those who lower their eyes." And signs of submission - like a gentle response, a soft voice and lowered eyes - remind him to have a submissive heart.

And they said in the Pesikta (of Rab Chana, Piska Deshuva Cant. Rabbah 1:5, letter 36. Yerushalmi ibid. And see Ta'anith 28b and Rashi ad. loc.) : If he was accustomed to eating after three hours let him eat after six, and if he used to eat after six hours let him eat after nine. And what is meant by, "And went softly" (I Kings 21:27)? Rabbi Joshua, the son of Levi, said that he walked barefoot, and from him (Ahab) every man should learn. Moreover (Pirke de-Rabbi Eliezer, chap. 43), go forth and learn from Manasseh, the son of Hezekiah, who did all the evil abominations in the world, yet the Holy One, Blessed be He, received him when he repented. Moreover (Sanh. 103a), Rabbi Johanan said, "Anyone who says that Manasseh has no share in the world to come weakens the hands of those who would repent. As a Tanna taught before Rabbi Johanan," Manasseh repented for thirty-three years and the Holy One, Blessed be He, received him.
