ISB ~ 2 Corinthians 5 v1

tent … building:A contrast between mortal bodies and resurrected bodies.

• An earthly tent is synonymous with a “perishable body” also in Wis 9:15. Beyond this, Paul has in mind the distinction between the Mosaic Tabernacle, a flimsy and temporary sanctuary used during Israel’s trek through the wilderness, and the Solomonic Temple, a building that became the permanent dwelling of God in Jerusalem. This transition from tent to building in biblical history helps to illustrate how our mortal bodies will give way to immortal ones on the last day (1 Cor 15:42-44).
