Isaiah 54:17 - Exposition

No weapon … every tongue. Whether weapons are used against Israel, or whether she is attacked, as in Sennacherib's time, by "the tongue that speaketh proud things" ( Isaiah 36:4-20 ; Isaiah 37:10-13 ), the result will he the same. She will triumph over her enemies, and condemn them or put them to shame. Her security is her righteousness , which she derives from Jehovah (comp. Isaiah 45:24 , Isaiah 45:25 ).
