1 Chronicles 16:39 - Joseph Benson’s Commentary on the Old and New Testaments

Zadok the priest Not the high-priest, but the second, and the chief priest at Gibeon, where the tabernacle and altar made by Moses still were, where also the ordinary sacrifices were offered, and the stated worship of God was performed, as the extraordinary worship was before the ark upon great occasions, as when God was consulted, which was to be done before the ark, and by the high-priest, who now was Abiathar, and who therefore abode with the ark, when Zadok was left at Gibeon.
