'Deadly' in the Bible

"Indeed, there are wicked scoundrels among my people. They lie in wait like bird catchers hiding in ambush. They set deadly traps to catch people.

Their tongues are like deadly arrows. They are always telling lies. Friendly words for their neighbors come from their mouths. But their minds are thinking up ways to trap them.

They will die of deadly diseases. No one will mourn for them. They will not be buried. Their dead bodies will lie like manure spread on the ground. They will be killed in war or die of starvation. Their corpses will be food for the birds and wild animals.
