International Standard Bible Encyclopedia
ze'-tham (zetham, meaning unknown): A Gershonite Levite (1Ch 23:8; 26:22). In the second passage Curtis holds that "the sons of Jehieli" is a gloss; he points the Massoretic Text to read "brethren" instead of "brother," and so has "Jehiel (1Ch 26:22) and his brethren, Zetham and Joel, were over the treasures."
