The Hebrew word for brother also means kin, neighbor, and friend.

Evidence

Ab is the brother, but it is also the family member, kin or relative, neighbor, and prochain. Ab is, finally, even the friend. And yet within the space of two very proximate verses, the biblical text itself introduces the distinction between “son of his brother” and “his brother,” thus demanding interpretation. — Gil Anidjar, The Jew, the Arab, 329

One must take into account the semantic field of that word, which enables the descriptions we have read so far and which does not therefore necessitate correction. Ab is the brother, but it is also the family member, kin or relative, neighbor, and prochain. Ab is, finally, even the friend. And yet within the space of two very proximate verses, the biblical text itself introduces the distinction between “son of his brother” and “his brother,” thus demanding interpretation. — Gil Anidjar, The Jew, the Arab, 329
