JMNT(i)
19 Jesus considered then responds to them, and says, "Loosen (or: Undo, and thus, destroy or demolish) this Sanctuary (Shrine; Divine Habitation; = the Temple consisting of the holy place and the holy of holies), and within three days I will proceed to be raising it up."
20 Then the Jews (= religious authorities) say, "This Sanctuary was built (constructed to be the House) and erected in (or: over a period of) forty-six years – and now you... you will proceed to be raising it up within three days?!"
21 Yet that One (= He) had been speaking about the Sanctuary (or: inner Temple; Divine habitation) which is His body.
