'Poison' in the Bible

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

“Their wine is the venom of serpents,And the deadly poison of cobras.

“For the arrows of the Almighty are within me,Their poison my spirit drinks;The terrors of God are arrayed against me.

“He sucks the poison of cobras;The viper’s tongue slays him.

They sharpen their tongues as a serpent;Poison of a viper is under their lips. Selah.

Do horses run on rocks?Or does one plow them with oxen?Yet you have turned justice into poisonAnd the fruit of righteousness into wormwood,
