C. F. Keil and Franz Delitzsch on Isaiah 39:2

Isa 39:2 “And Hezekiah rejoiced (K.heard, which is quite inappropriate)concerning them, and showed them (K.all)his storehouse: the silver, and the gold, and the spices, and the fine oil (hasshâmen ,K.shemen), and all his arsenal, and all that was in his treasures: there was nothing that Hezekiah had not shown them, in his house or in all his kingdom.” Although there were spices kept in נכת בּית, נכת is not equivalent to נכאת (from נכא, to break to pieces, to pulverize), which is applied to gum-dragon and other drugs, but is the niphal נכת from כּוּת (piel, Arab. kayyata, to cram full, related to כּוּס (כּיס), נכס (נכס), and possibly also to כּתם, katama (Hitzig, Knobel, Fürst), and consequently it does not mean “the house of his spices,” as Aquila, Symmachus, and the Vulgate render it, but his “treasure-house or storehouse” (Targ., Syr., Saad.). It differs, however, from bēth kēilim, the wood house of Lebanon (Isa 22:8). He was able to show them all that was worth seeing “in his whole kingdom,” inasmuch as it was all concentrated in Jerusalem, the capital.
