Romans 3:14 describes the speech of people who have turned away from God: their mouths are full of cursing and bitterness. Paul is not singling out a few bad people here. He is quoting a string of Old Testament passages to show that every human being, Jew and Gentile alike, stands under sin. The words come from Paul’s own letter to the church in Rome, written in the middle of his argument that all people need God’s righteousness.
“whose mouth is full of cursing and bitterness.”

What Romans 3:14 Means
The phrase “their mouth” points to what comes out of a person. Speech is one of the clearest windows into the heart, because words reveal what a person really values and resents. Paul says the mouth is “full,” which suggests not an occasional slip but a supply that never runs out. Cursing is speech that wishes harm or calls down evil on someone. Bitterness is the resentful, sour spirit that keeps score and poisons conversation.
The verse does not promise that every person curses constantly or that no one can speak kindly. It is a diagnosis of the condition Paul has been building throughout this section, not a description of every single conversation. Its purpose is to show that words are symptoms of a deeper problem, and that no human effort can fully cure it on its own.
The Context of Romans 3:14
Paul wrote Romans around the middle of the first century to a mixed congregation of Jewish and Gentile believers in Rome. He had not founded that church, and his letter lays out the gospel as he understood it in full. Chapters 1 through 3 make the case that everyone, whether they knew the Jewish law or not, has fallen short of God’s glory. Romans 3:10 to 18 gathers a chain of quotations from the Psalms, Ecclesiastes and Isaiah, and verse 14 is one link in that chain.
Read in its setting, the verse is not an attack on a particular group but a summary of universal human failure. The sentences just before it describe people who do not understand and do not seek God, and the sentences after it describe violence and a way of life that has never known peace. Seen this way, the mouth full of cursing is one visible sign of a heart that has turned away, and Paul’s goal is to bring every listener, including the one who feels righteous, to see the need for grace.
Key Phrases in Romans 3:14
James 3:9-10
9 With it we bless our God and Father, and with it we curse men, who are made in the image of God. 10 Out of the same mouth comes blessing and cursing. My brothers, these things ought not to be so.

James makes the same point from a different angle, noting that the same tongue can bless God and curse people made in his image. His sharp contrast shows why Paul’s diagnosis matters: speech that wounds others is a serious inconsistency for anyone who claims to honor God.
Ephesians 4:31-32
31 Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. 32 And be kind to one another, tender hearted, forgiving each other, just as God also in Christ forgave you.
(WEB)
Paul’s own later letter names bitterness directly and calls believers to put it away, replacing it with kindness and forgiveness. Reading it alongside Romans 3:14 shows the movement from diagnosis to the new life that God gives through Christ.
A Short Prayer From Romans 3:14
Lord, you see the words I have spoken in anger and the bitterness I have kept hidden in my heart. I confess that my mouth can be full of things that do not honor you or bless others. Search me and show me the roots of the resentment I carry. Cleanse my heart so that my words might come from a place of love and truth. Thank you that you are patient with my failures and that you offer me a new heart through Jesus. Teach me to speak what builds up and to release what wounds. Amen.
