ez'-ra-hit ('ezrachi; Asebon):
Found in1Ki 4:31;Psalm 88;Psalm 89, titles; from which it appears that the word is a patronymic for Ethan and Heman. It may be derived from Zerah, instead of Ezrah, seeing that there were an Ethan and a Heman who were descendants of Zerah, head of a Judahite family (1Ch 2:6).
There were also an Ethan and a Heman who were Levites (1Ch 15:17).
