'Poisonous' in the Bible

so that there will not be among you a man or woman, or family or tribe, whose heart turns away today from the Lord our God, to go and serve the [false] gods of these nations; so that there will not be among you a root [of idolatry] bearing poisonous fruit and wormwood (bitterness).

‘They will be wasted by hunger, and consumed by plagueAnd a bitter destruction;And I will send the teeth of beasts against them,With the venom of crawling things of the dust.

“For their vine is from the vine of Sodom,And from the fields of Gomorrah;Their grapes are grapes of poison,Their clusters, bitter.
