Jeremiah 4:22 says that God’s people have become foolish because they do not know him, and that their cleverness is turned toward wrongdoing while they have forgotten how to do what is good. The prophet Jeremiah speaks these words on God’s behalf to the people of Judah, shortly before the nation faced invasion and exile in the early sixth century BC.
“For my people are foolish. They don’t know me. They are foolish children, and they have no understanding. They are skillful in doing evil, but they don’t know how to do good.”

What Jeremiah 4:22 Means
The verse begins with a diagnosis rather than a command. God calls his people “foolish,” but the word points less to low intelligence than to a settled habit of ignoring what is true and wise. The second sentence explains the cause: they do not know God. In the Hebrew sense of knowing, this means a relationship of trust and obedience, not merely having information about him. The next image, “foolish children” with “no understanding,” describes immaturity that refuses to learn.
The final sentence is the sharpest. These people are “skillful in doing evil,” which means they have become practiced and clever at harmful things, yet they “don’t know how to do good.” The verse does not say they can never do good or that God has abandoned them forever. It describes a condition they have chosen and that has shaped their skills, and the prophet’s larger message is a call to return.
The Context of Jeremiah 4:22
The book of Jeremiah is traditionally attributed to the prophet Jeremiah, who ministered in Jerusalem during the final decades before the Babylonian conquest of 586 BC. His audience was the people of Judah, including their leaders, priests and ordinary families, who had drifted into idolatry and social injustice while trusting in the temple as a guarantee of safety. Jeremiah 4 is full of warning, and verses 19 through 21 show the prophet himself in anguish at the sound of approaching war.
Verse 22 sits in the middle of that grief. The verses that follow, 23 through 25, describe the land as empty and waste, a picture of judgment already underway. Reading the verse in this setting shows that it is not a casual insult. It is the honest explanation a grieving prophet gives for why the disaster is coming, and it carries an undertone of sorrow rather than contempt.

A Short Prayer From Jeremiah 4:22
Lord, you know how easily I become skilled at the wrong things, at defending myself, at winning, at managing my own image. Open my eyes where I have grown foolish and show me the places where I have forgotten you. Teach me to know you more deeply, so that my understanding is shaped by your truth and my hands learn again how to do good. Where I have grown hard, soften me, and where I have drifted, bring me home. Amen.
