וְאָכַלְתָּ֣ פְרִֽי־בִטְנְךָ֗ בְּשַׂ֤ר בָּנֶ֙יךָ֙ וּבְנֹתֶ֔יךָ אֲשֶׁ֥ר נָֽתַן־לְךָ֖ יְהוָ֣ה אֱלֹהֶ֑יךָ בְּמָצוֹר֙ וּבְמָצ֔וֹק אֲשֶׁר־יָצִ֥יק לְךָ֖ אֹיְבֶֽךָ׃
And thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters whom the LORD thy God hath given thee; in the siege and in the straitness, wherewith thine enemies shall straiten thee.
Targum Jonathan on Deuteronomy
And the children of your wombs shall be consumed; for you will eat them in the famine, even the flesh of your sons and daughters, whom the Lord your God did give you, by reason of the anguish and oppression wherewith your enemies shall oppress you.
