He made three hundred shields - The מגן magen was a large shield by which the whole body was protected.
Mr. Reynolds computes that the two hundred targets, on each of which were employed three hundred shekels of gold, were worth £28,131 16s. 9 1/2d.
And the three hundred shields, in forming each of which three pounds of gold were employed, were worth £210,976 7s. 7d.
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” 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.
