Jamieson, Fausset and Brown on Isaiah 60:13

13. glory--that is, the trees which adorned Lebanon; emblem of men eminent in natural gifts, devoting all that is in them to the God of Israel (Ho 14:5, 6).

fir ... pine ... box--rather, "the cypress ... ilex ... cedar."

place of my sanctuary--Jerusalem (Jr 3:17).

place of my feet--no longer the ark (Jr 3:16), "the footstool" of Jehovah (Psa 99:5; 132:7; 1Ch 28:2); but "the place of His throne, the place of the soles of His feet, where He will dwell in the midst of the children of Israel for ever," in the new temple (Eze 43:7).
