וְאִם־אֵ֥ין ל֖וֹ אַחִ֑ים וּנְתַתֶּ֥ם אֶת־נַחֲלָת֖וֹ לַאֲחֵ֥י אָבִֽיו׃
형제도 없거든 그 기업을 그 아비의 형제에게 줄 것이요
Bartenura
והאחין מן האב – as it is written (Numbers 27:10): “in his own clan, and he shall inherit it.” And the family/clan of the father is called a family, as it is written (Numbers 1:2): “by the clans of its ancestral houses.”
