וְהָיָ֗ה הַבְּכוֹר֙ אֲשֶׁ֣ר תֵּלֵ֔ד יָק֕וּם עַל־שֵׁ֥ם אָחִ֖יו הַמֵּ֑ת וְלֹֽא־יִמָּחֶ֥ה שְׁמ֖וֹ מִיִּשְׂרָאֵֽל׃
And it shall be, that the first-born that she beareth shall succeed in the name of his brother that is dead, that his name be not blotted out of Israel.
Targum Jonathan on Deuteronomy
And the first-born whom she beareth shall stand in the inheritance in the name of the deceased brother, that his name may not be blotted out from Israel.
