Rashi, on Isa 22:6

“And Elam took the quiver, the chariot of the horseman, and the shield was taken down from the wall.”

“carried a quiver a quiver of arrows. and to the wall they attached their shields (עֵרָה). Comp. (above 19:7) “The well rooted plants (עָרוֹת) by the stream,” (Psalms 37:35) “Striking roots (מִתְעָרֶה) like a green tree in its native soil.” It is also possible to explain: וְקִיר עֵרָה מָגֵן as follows: Kir is the name of the city. Comp. (II Kings 16:9) “And exiled [its inhabitants] to Kir.” The people of that province exposed their shields toward Jerusalem.”
