הלכה אויף ירמיהו 31:19

What is repentance? The sinner shall cease sinning, and remove sin from his thoughts, and wholeheartedly conclude not to revert back to it, even as it is said: "Let the wicked forsake his way" (Is. 55.7); so, too, shall he be remorseful on what was past, even as it is said: "Surely after that I was turned, I repented" (Jer. 31. 19). In addition thereto he should take to witness Him Who knoweth all secrets that forever he will not turn to repeat that sin again, according to what it is said: "Say unto Him.… neither will we call any more the work of our hands our gods" (Hos. 14.3–4). It is, moreover, essential that his confession shall be by spoken words of his lips, and all that which he concluded in his heart shall be formed in speech.²Yoma, 57b; Shabbat, 121. G.

We may not mention malkhiot, zikhronot and shofarot of punishment — such as [in] zikhronot, "And all flesh shall remember that, etc." (Psalms 78:39); [in] malkhiot, "with outpoured anger shall I rule over you" (Ezekiel 20:33); [and in] shofarot, "Blow the shofar on the mountain, etc." (Hosea 5:8). Nor [may we mention] the remembrance of an individual — even if it was for good — such as "Remember me, O Lord, in the desire of Your people" (Psalms 106:4); and "Remember me, my God, for the good" (Nehemiah 13:31). And recollections (pikdonot) — such as "I have surely recalled you" (Exodus 3:16) — are not the same as remembrances. But one may mention the punishment of idolatrous nations, such as "The Lord reigned, nations tremble" (Psalms 99:1); "Remember the day of Jerusalem to the Children of Edom" (Psalms 137:7); [and] "the Lord, God, will blow with the shofar, and go in the storms of the south" (Zechariah 9:14). All of these verses: "Hear Israel, the Lord, our God, the Lord is one" (Deuteronomy 6:4); "You have been shown to know" (Deuteronomy 4:35); "And you shall know today and place upon your hearts, etc." (Deuteronomy 4:39) — their content is kingship. Even though there is no mention of kingship [in them], it is surely like, "The Lord will reign forever and ever" (Exodus 15:18); [and] "And then He became King in Jeshurun, etc." (Deuteronomy 33:5).

On New Year, the section is that beginning, "And in the seventh month, on the first day of the month" (Numbers 29:1). It is however a general custom to read on the first day the section beginning, "And the Lord remembered Sarah" (Genesis 21:1-34); and the lesson from the Prophets is that beginning, "Now there was a certain man of Ramathaim—zophim" (I Samuel 1:1-2:10). On the second day, the section read is that beginning, "And it came to pass after these things that God did prove Abraham" (Genesis 22:1-24); and the lesson from the Prophets is that concluding, "Is Ephraim a darling son unto me" (Jeremiah 31:1-19).
