Midrasz do Samuela I 25:38

R. Samuel b. lnya said in the name of Rab: "Whence do we know that a decree against a community is not confirmed." Is that true? Behold, it is written (Jer. 2, 22) The stain of thy sin remains before Me. But this is what he meant: Whence do we know that a decree issued against a community, even if confirmed, may nevertheless be cancelled? From the passage (Deut. 4, 7) As the Lord, our God, in all things that we call upon Him for. But it is also written (Isa. 55, 6) Seek ye the Lord while He may be found. Hence, is there a difference? The latter passage refers to an individual, the former to a community. When is the proper time for an individual [to repent]? R. Nachman, in the name of Rabba b. Abahu, said: "The ten days of repentence, between New Year's Day and the Day of Atonement." (I Sam. 25, 38) And it came to pass, in about ten days thereafter, that the Lord smote Nabal. What is the reason for the ten days' waiting? R. Juda, in the name of Rab, said: "It corresponds to the ten meals which Nabal gave to David's servants." And R. Nachman, in the name of Rab, said: "This refers to the ten days of penitence [given to Nabal in which to repent]."
