וְהָיָ֡ה בְּשָׁמְעוֹ֩ אֶת־דִּבְרֵ֨י הָֽאָלָ֜ה הַזֹּ֗את וְהִתְבָּרֵ֨ךְ בִּלְבָב֤וֹ לֵאמֹר֙ שָׁל֣וֹם יִֽהְיֶה־לִּ֔י כִּ֛י בִּשְׁרִר֥וּת לִבִּ֖י אֵלֵ֑ךְ לְמַ֛עַן סְפ֥וֹת הָרָוָ֖ה אֶת־הַצְּמֵאָֽה׃
너희 중에 남자나 여자나 가족이나 지파나 오늘날 그 마음이 우리 하나님 여호와를 떠나서 그 모든 민족의 신들에게 가서 섬길까 염려하며 독초와 쑥의 뿌리가 너희 중에 생겨서
Rashi
והתברך בלבבו AND HE BLESS HIMSELF IN HIS HEART — The word והתברך has the meaning of “blessing”. In his heart he will imagine for himself a blessing of peace, saying, “These curses will not come upon me, I shall have peace”.
Chizkuni
את דברי האלה הזאת, “the words of this curse.” This is a reference to the curses pronounced at Mount Eyval, in chapter 27, 15-26.
Da'at Zekenim
והיה בשמעו את דברי האלה הזאת וגו, “and when he hears the wording of this curse [which appeared to him as addressed to the community, as opposed to individuals in the community, Ed.] והתברך, “and he will personally feel immune in his heart;” שלום יהיה לי, “I, personally will be quite safe;” בשרירות לבי אלך, ”and therefore I will follow whatever my heart dictates to me;” למען ספות הרוה את הצמאה, “so that the irrigated will be swept away with the dry;” [the sinner’s logic is that on account of one single sinner G–d will not withhold blessings such as rain from a whole community. Ed.] Alternate meaning, the author’s: “he will commit sins that are not the result of the evil urge as well as sins that are the result of his evil urge.” לא יאבה ה' סלוח לו, כי אז יעשן אף ה' וקנאתו, “not only will the Lord not consider forgiving him his foolishness, but His anger and jealousy will be kindled against such an individual and He will single him out for especially harsh punishment. By doing this the remainder of you will be shielded against copying his conduct, and you will remain loyal to G–d’s covenant. For if you collectively would fail to remain loyal ורבצה בו כל האלה, “the Lord will blot out his name,” so that no descendants of such a sinner will remain alive under the sky. Neither an already an existing grandson or great-grandson will be allowed to live. והבדילו ה' לרעה, “and the Lord will single him out for misfortune; that sinner had thought that he alone of all the Israelites could get away with being disloyal to the covenant. I will show the Israelites that he alone will be singled out for such harsh treatment by Me. The punishment will fit the crime.
