je-hoi'-a-rib (yehoyaribh, "Yahweh pleads" or "contends"): A priest in Jerusalem (1Ch 9:10); the name occurs again in 1Ch 24:7 as the name of a family among. the 24 courses of priests = the family Joiarib (yoyaribh, same meaning as above, Ne 1:2,6), the head of which is Matrenai in Ne 12:19. In Ne 11:10 we should probably read ""Jedaiah and Joiarib" for "Jedaiah the son of Joiarib" (compare 1Ch 9:10). Jehoiarib = Joarib in 1 Macc 2:1.
