hak'-oz (haqqots, or ha-qots, "the nimble"):
(1) A priest and chief of the 7th course of Aaron's sons selected by David (1Ch 24:10). According to Ezr 2:61; Ne 3:4,21; 7:63, his descendants returned with Zerubbabel from the captivity. But the King James Version considers the name in Ezra and Nehemiah as having the article prefixed, hence renders "Koz."
(2) One of Judah's descendants (1Ch 4:8).
