וַנֹּ֙אמֶר֙ אֶל־אֲדֹנִ֔י יֶשׁ־לָ֙נוּ֙ אָ֣ב זָקֵ֔ן וְיֶ֥לֶד זְקֻנִ֖ים קָטָ֑ן וְאָחִ֨יו מֵ֜ת וַיִּוָּתֵ֨ר ה֧וּא לְבַדּ֛וֹ לְאִמּ֖וֹ וְאָבִ֥יו אֲהֵבֽוֹ׃

And we said unto my lord: We have a father, an old man, and a child of his old age, a little one; and his brother is dead, and he alone is left of his mother, and his father loveth him.
