(`abhdi, probably by abbreviation "servant of Yahweh"):
(1) A Levite, father of Kishi and grandfather of King David’s singer Ethan (1Ch 6:44; compare 1Ch 15:17). This makes Abdi a contemporary of Saul the king.
(2) A Levite, father of the Kish who was in service at the beginning of the reign of Hezekiah (2Ch 29:12). Some mistakenly identify this Abdi with the former.
(3) A man who in Ezra’s time had married a foreign wife (Ezr 10:26). Not a Levite, but "of the sons of Elam."
