ay.yah is a personal name used for a son of Zibeon and for Rizpah's father.

The attested uses are all proper-name references: most identify Aiah as Rizpah's father in the Saul narratives, while two genealogical verses list Aiah as a son of Zibeon.

1. Rizpah's father · dominant

   In 2 Samuel 3:7 the proper noun identifies Rizpah as the daughter of Aiah. The same paternal identification frames the account of her sons in 2 Samuel 21:8 and her actions in 2 Samuel 21:10; 2 Samuel 21:11 again calls her “Rizpah daughter of Aiah.”

2. Son of Zibeon in genealogical listing · common

   In Genesis 36:24 the APB renders a list of Zibeon's sons as “Aiah and Anah.” 1 Chronicles 1:40 likewise places Aiah among “The sons of Zibeon,” preserving the name in a genealogical setting.

   Genesis 36:241 Chronicles 1:40

In the Anselm Project Bible: The APB presents the name directly as “Aiah” in the genealogical lists and in the repeated designation “daughter of Aiah.” These English forms are treated as its presentation of the personal name within the clauses.
