1 Chronicles 16:39

39. Zadok the priest, and his brethren the priests, before the tabernacle… at Gibeon The tabernacle had probably been removed to the high place at Gibeon soon after the slaughter of the priests at Nob, 1 Samuel 22:19; and Zadok had, perhaps, been appointed high priest during the latter years of Saul’s reign. So David did not interfere with the worship at Gibeon, but left (1 Chronicles 16:37) Zadok there to minister as high priest, and to carry on the regular tabernacle service and the offering of burnt offerings. At the same time, however, he provided for a regular service before the ark in the new tabernacle on Zion, and thus furnished a charge for Abiathar, his old friend, and faithful companion in the days of his exile. 1 Samuel 22:20-23. Thus matters continued until the time of Solomon, who deposed Abiathar, (1 Kings 2:26,) and after the building of the temple transferred all the sanctuary service thither. 1 Kings 8:4. Comp. note on 2 Samuel 6:17.
