Tabernacle; c.1250, "portable sanctuary carried by the Israelites in the wilderness," from O.Fr. tabernacle (12c.), from L. tabernaculum "tent," especially "a tent of an augur" (for taking observations), dim. of taberna "hut, cabin, booth". Transferred 1388 to the Temple in Jerusalem. www.etymonline.com
And
I think it right, as long as I am in this tabernacle, to stir you up by putting
you in remembrance;
knowing that the putting off of my tabernacle cometh swiftly, even as our Lord
Jesus Christ signified unto me.
2Pe 1;13

It in fact applies to all of us. (or at least; it could.)
The term sometimes is applied to angels as in the case of Israel the guardian angel of Jacob who said to have tabernacled among men.
Since angels are people who died and went to heaven ...
For in the resurrection they ... are like angels in heaven. Mt 22;30
tabernacling is just an other word for Reincarnation with the difference that these people knew that they were reincarnated, while most of us don't.
