1 Chronicles 16:39 - Clarke's commentary and critical notes on the Bible

And Zadok the priest, and his brethren the priests, before the tabernacle of the LORD in the high place that was at Gibeon, Zadok the priest - Both Zadok and Abiathar were high priests at this time: the former David established at Gibeah, or Gibeon, where the ark had been all the days of Saul; and the latter he established at Jerusalem, where the ark now was: so there were two high priests, and two distinct services; but there was only one ark. How long the service at Gibeon was continued we cannot tell; the principal functions were no doubt performed at Jerusalem.
