'Worst' in the Bible

“His skin is devoured by disease;The firstborn of death [the worst of diseases] consumes his limbs.

All who hate me whisper together about me;Against me they devise my hurt [imagining the worst for me], saying,

“Be broken [in pieces], O peoples, and be shattered!Listen, all you [our enemies from the] far countries.Prepare yourselves [for war], and be shattered;Prepare yourselves [for war], and be shattered.

They are all the worst [kind] of [stiff-necked, godless] rebels,Going around spreading slander.They are [not gold and silver ore, but] bronze and iron;They are all corrupt.

Therefore, I will bring the worst of the [Gentile] nations, and they will take possession of their houses [those of the people of Judah]; I will also silence their pride, and their holy places will be profaned.
