breastplate a piece of armor covering the chest to protect it against blows and arrows
8.38 · Body, Body Parts, and Body Products · Parts of the Body
chest the portion of the upper trunk covered by the breastplate Note, however, that in REV 9:9 it is possible to understand the first occurrence of θώραξ in the sense of ‘breastplate,’ the meaning which it normally has in other biblical contexts (for example, EPH 6:14 and 1TH 5:8). The passage could then be translated as ‘their breastplates were iron breastplates’ (see 6.39).
