1 Chronicles 16:39 -

While those above-mentioned were to officiate before the ark on Zion, those mentioned in this and following verses are the officiating staff at Gibson. It is now brought into prominence that the ark and the tabernacle are in two separate places. The great ordinary sacrifices and services, "all that is written in the Law of the Lord," are carefully observed on the original altar ( Exodus 38:2 ) in the tabernacle. Other and special sacrifices evidently were offered in the presence of the ark. The tabernacle erected in the wilderness was first stationed at Shiloh ( Joshua 18:1 ; 1 Samuel 4:3 , 1 Samuel 4:4 ). The occasion of its removal to Nob ( 1 Samuel 21:1 ; 1 Samuel 22:19 ) is not narrated. The present passage first tells us where it had been since the slaughter of the priests at Saul's command by Doeg the Edomite. Some distinct statement, like that of 1 Chronicles 21:29 and 2 Chronicles 1:3 , might have been expected here . Zadok the priest is given ( 1 Chronicles 6:4-9 ) as in the line of Eleazar.
