Parallel
Isaiah 33:19
Brenton's English Septuagint · Berean Standard Bible
[even] the small and great people? with whom he took not counsel, neither did he understand [a people] of deep speech, so that a despised people should not hear, and there is no understanding to him that hears.
You will no longer see the insolent, a people whose speech is unintelligible, who stammer in a language you cannot understand.
