‘In SALEM is His tabernacle... And His dwelling place in ZION’ (Psalm 76)

Note: The words above from Psalm 76 are typical Hebrew poetic parallelism and means therefore, that Salem and Zion are the same place.
 
Asaph who penned these words, was a prominent Levite singer and seer in David’s court and was the son of Berachiah of the tribe of Levi.
His song mentions the tabernacle or tent which has to be the tent David pitched at Gihon to house the ark and the sacred items, including the anointing oil.
We notice that Asaph uses the very ancient name for this special site where the ‘priest of God most high’ dwelt—yes Melchizedek—who came out to meet Abraham and to bless him.
 
Asaph sees the site, with the tent and the presence of God dwelling there as the centre from which the enemies of Israel met their destruction. It was the earthly throne of Yahweh.
 
Asaph identifies the ancient Salem of Melchizedek with Zion and both are associated with the ‘tabernacle.’ This can only be the tent erected by David after he took Zion which he then called the City of David.
We know that this tent (or tabernacle) was at Gihon.
As the sacred site, recognised by David--the site that had been occupied by Melchizedek, the precursor and 'type' of Messiah, it was where the permanent temple must have been erected.
