וּבָ֛א הַמֶּ֥לֶךְ דָּוִ֖ד עַד־בַּֽחוּרִ֑ים וְהִנֵּ֣ה מִשָּׁם֩ אִ֨ישׁ יוֹצֵ֜א מִמִּשְׁפַּ֣חַת בֵּית־שָׁא֗וּל וּשְׁמוֹ֙ שִׁמְעִ֣י בֶן־גֵּרָ֔א יֹצֵ֥א יָצ֖וֹא וּמְקַלֵּֽל׃
大衛王來到巴戶琳，看哪，有一個人從那裡出來，是掃羅家族的人，名叫示每，是基拉的兒子；他一邊走出來，一邊不停地咒罵。
Rashi
Lest you hear your own servant curse you. It is not good that you incline your ear to hear your servant cursing you.52As Dovid did with Shimi the son of Geira. See II Shmuel 16:5-13. (Sifsei Chachomim)
Rashi
כי קללת אלהים תלוי FOR HE THAT IS HANGED IS A קללת אלהים — i.e., a degradation of the Divine King, for man is made in His image and the Israelites are His children. A parable! It may be compared to the case of two twin brothers who very closely resembled each other: one became king and the other was arrested for robbery and was hanged. Whoever saw him on the gallows thought that the king was hanged (Sanhedrin 46b). — Wherever the term קללה occurs in Scripture it has the meaning of bonding in light esteem and despising, as e.g., (1 Kings 2:8) “[Shimei the son of Gera, a Benjamite of Bahurim] who cursed me with a severe curse (קללני קללה נמרצת)” (cf. II Samuel 16:5—8).
