Ishijah
Ishijah (UPDV: "Isshijah") appears once, in the post-exilic list of those who had married foreign women.
A Son of Harim
The name stands second in the Harim sub-list of Ezra's roster of separations: "And [of] the sons of Harim: Eliezer, Isshijah, Malchijah, Shemaiah, Shimeon," (Ezr 10:31). The bracketed [of] is a translator-supplied connector matching the form of the surrounding entries. The notice is purely registrational — Isshijah is one named entry in a longer accountability list.
