וַיִּרְגַּ֣ז הַמֶּ֗לֶךְ וַיַּ֛עַל עַל־עֲלִיַּ֥ת הַשַּׁ֖עַר וַיֵּ֑בְךְּ וְכֹ֣ה ׀ אָמַ֣ר בְּלֶכְתּ֗וֹ בְּנִ֤י אַבְשָׁלוֹם֙ בְּנִ֣י בְנִ֣י אַבְשָׁל֔וֹם מִֽי־יִתֵּ֤ן מוּתִי֙ אֲנִ֣י תַחְתֶּ֔יךָ אַבְשָׁל֖וֹם בְּנִ֥י בְנִֽי׃
Maka raja sangat terguncang. Ia naik ke kamar di atas pintu gerbang dan menangis. Sambil berjalan ia berkata, “Anakku Absalom, anakku, anakku Absalom! Sekiranya aku saja yang mati menggantikan engkau, Absalom, anakku, anakku!”
Or HaChaim
According to this principle they mentioned their children last, as those represented the future and as such deserved the highest priority in their considerations (compare David rating Absalom's life as more important than his own even while Absalom sought to kill his father (Samuel II 19,1).
Rashi
ממתנו means THAN THAT WE SHOULD DIE. If the word had been punctuated with a Melopum (our חולם i. e. מִמּוֹתֵנוּ) it would have to be explained “than our death” (מוֹתֵנוּ our death from the noun מָוֶת) but now that it is punctuated with a שורק (our Kibbutz) it must be explained by “than that we should die”. And similar is, (Exodus 16:3) “Would that מוּתֵנוּ” i. e. “that we should die”; similar is, (II Samuel 19:1) “Would that מוּתִי” in the history of Absalom, which means “that I should die”. It is an infinitive like (Zephaniah 3:8) “Until the day קוּמִי for ever”, and as (II Chronicles 18:26) “Until the day שׁוּבִי in peace” — which signify שאקום “that I shall arise”, and שאשוב “that I shall return”.
