וַאֲכַלְתֶּ֖ם בְּשַׂ֣ר בְּנֵיכֶ֑ם וּבְשַׂ֥ר בְּנֹתֵיכֶ֖ם תֹּאכֵֽלוּ׃
너희가 아들의 고기를 먹을 것이요 딸의 고기를 먹을 것이며
Or HaChaim
ואכלתם בשר בניכם, "and you will eat the flesh of your own sons." The reason the Torah repeats this statement by also writing: "you will eat the flesh of your daughters" is to tell you that even after having eaten the flesh of their sons their pity will not have been stirred and they will continue by eating the flesh of their daughters.
Rav Hirsch
V. 29. ואכלתם בשר וגו׳. Es geht ihm das ונאספתם וגו׳ ,והבאתי עליכם חרב וגו׳ בשברי לכם וגו׳ des vorhergehenden Verhängnisses zuvor, und setzt sich dies hier nur mit dem unheilvoll gesteigerten Ausgang dieser letzten Katastrophe fort! ובשר בנותיכם וגו׳ scheint noch eine Steigerung in dem Gräßlichen zu sein.
Chizkuni
ואכלתם בשר בניכם, “you will eat the flesh of your children.” This curse corresponds to the blessing in verse 9 והפרתי אתכם, “I will make you fruitful.”Some commentators understand this as referring to children who are from highly respected families getting married to families of far lower social standing, by trading their superior ancestry for making an alliance with a wealthier family through marriage. If so, this would be the first curse.
