   In Joshua 15:32, Joshua 19:7, and 1 Chronicles 4:32, the proper-noun form occurs among named cities; the APB renders each list with “Ain.” In Joshua 21:16 the APB includes “Ain and its pasture,” while in Numbers 34:11 it locates Riblah east of Ain as the border goes down.

In the Anselm Project Bible: The APB consistently presents the proper name as “Ain,” whether it occurs in city lists, with its pasture, or as a boundary landmark. This consistency confirms the verse-level presentation rather than a separate lexical rendering.
