The imagery here isn't just about what people say, but the very source and intent behind their words. The "open grave" and "venom of asps" aren't merely describing bad language, but the deadliness and hidden corruption that spews forth from a heart truly alienated from God.
“Their throat is an open grave; they use their tongues to deceive.” “The venom of asps is under their lips.” “Their mouth is full of curses and bitterness.”
English Standard Version (ESV)
Paul is presenting overwhelming evidence from Scripture that no one, Jew or Gentile, is righteous before God; he's showing how sin has corrupted humanity universally. These verses, drawn from Old Testament Psalms, describe the destructive nature of ungodly speech, revealing how lies, slander, and deceit spew from the mouths of those enslaved by sin. This paints a grim picture of humanity's fallen condition, setting the stage for God's solution found in the gospel.

It is compared to a “yawning grave”—not merely to a pit into which a man may fall, but to a sort of pestiferous chasm yawning and ravening, as it were, after its prey.
