These shields, together with the 500 taken by David from Hadadezer 2 Samuel 8:7 were hung round the outer walls of a building, reckoned as belonging to the “house of the Forest of Lebanon,” but separate from it, and called sometimes “the Tower of David” Song of Solomon 4:4, or from its use “the armoury” Song of Solomon 4:4; Isaiah 22:8. The practice of hanging shields outside walls for ornamentation seems to have existed at Tyre Ezekiel 27:10-11, Rome, Athens, and elsewhere. Traces of it are thought to be found in the Assyrian sculptures.
