Blood Sacrifice at David's Tabernacle

Likely to protect The Ark of the Testimony, which had been stolen numerous times by other nations, David kept it near himself at Mount Zion and set up a tent for it, commonly called The Tabernacle of David.  Although this new location stood apart from the Tent of Meeting which continued to stand in Gibeon, worship practices did not change much in Israel because of it. 

For example, there were blood sacrifices offered before the Tabernacle of David the day the Ark was placed there. (1 Chronicles 15:29-16:3) The only outstanding change from the traditional patterns of Mosaic worship was the addition of musical Levites under Asaph who sang and played at the tent where the Ark was stored. (1 Chronicles 16:4-6).

Also, the Day of Atonement continued, which involved bringing the blood from the bull and the goat at Gibeon (1 Chronicles 16:40) to the Ark at Zion for the sprinkling of blood (1 Chronicles 6:31-32, 48-49), as prescribed in Leviticus 16:11-17. 

Other connections continued between (Moses') Tent of Meeting and the Tabernacle of David.  For example, all the formerly prescribed sacrifices and petitions continued in Gibeon, with Zadok as high priest, but also with the addition of singers and musicians for the ceremonies there, under Heman. (1 Chronicles 16:39-42)

So, there were two meeting places.  One had the primary purpose of sacrifices and prayer, but included the added presence of musical worship.  The other had the primary purpose of musical worship and petition, but also included the prescribed blood and incense ceremonies.  Once the permanent, more secure, building of Solomon's Temple was erected, both venues were once again brought together as a single place of worship. 

It is encouraging to see how God finds ways, through his servants, to maintain the integrity of true worship in the face of changing political times.
