יְהִֽי־אַחֲרִית֥וֹ לְהַכְרִ֑ית בְּד֥וֹר אַ֝חֵ֗ר יִמַּ֥ח שְׁמָֽם׃
Que sa postérité soit condamnée à disparaître, qu’à la génération prochaine son nom soit éteint.
Sforno
ותהי אחריתי כמוהו, so that my offspring be like that of the Israelites. The children of man and those who are the biological issue of him are known as אחריתו, [literally the ones who are following behind him. Ed.] We encounter the word אחרית in this sense in Psalms 109,13 תהי אחריתו להכרית, “may his posterity be cut off. We encounter it in this context also in Daniel 11,4 ולא לאחריתו, “but not for any of his posterity.”
