Ezrahite

EZRAHITE (ĕz'ra-hīt, Heb. ’ezrāhî). Designation of Ethan and Heman (1Kgs.4.31; titles of Ps.88.1-Ps.88.18-Ps.89.1-Ps.89.52).

International Standard Bible Encyclopedia (1915)

(’ezrachi; Asebon):

Found in 1Ki 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).
