ZETHAM (zē'thăm, Heb. zethām, olive tree). A Gershonite Levite in David’s time. He was son of Ladan (1Chr.23.8; Laadan kjv, neb) or the son of Jehieli (1Chr.26.22); perhaps one was actually his grandfather.
ZETHAM ze’ thəm (זֵתָ֥ם). A Gershonite Levite; house of Ladan and son of Jehiel (1 Chron 23:8; 26:22).
International Standard Bible Encyclopedia (1915)
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."
