This personal name appears in two post-exilic contexts, identifying different individuals. Ezra 10:30 lists Adna among those who had married foreign wives during the exile and were required to divorce them. Nehemiah 12:15 names an Adna as head of a priestly family in the generation after the return. The name likely means 'delight' or 'pleasure,' from the same root as Eden. Both occurrences reflect the reconstituted community's attention to genealogical and covenantal purity.
