Ezril was a man who had married a foreign wife after the exile and was required to put her away. He is identified with Azarel in Ezra.
Ezril is named in 1 Esdras 9:34 among those who had taken foreign wives. The parallel name in Ezra 10:41 is Azarel.
Ezril and Esril are variant forms of the name in the textual tradition. The account belongs to the postexilic reform concerning foreign marriages.
