Isaiah 5:20 is a warning against moral confusion, where people redefine right and wrong to suit themselves and reverse what God calls good and evil. The prophet Isaiah speaks it to the people of Judah, as a message of judgment against those who treat sin as harmless and holiness as foolish.
Woe to those who call evil good, and good evil; who put darkness for light, and light for darkness; who put bitter for sweet, and sweet for bitter!

What Isaiah 5:20 Means
The verse opens with “Woe,” a prophetic cry of grief and warning rather than a curse flung in anger. Isaiah is saying that those who do this are heading toward trouble, and that God takes their confusion seriously. The reversal is the heart of it: “call evil good, and good evil” describes people who relabel wrongdoing with pleasant words and treat genuine goodness as something to mock or dismiss.
The next pairs of images, darkness for light and bitter for sweet, make the point physically. Darkness cannot be mistaken for light by anyone who is actually looking, and bitter food cannot be mistaken for sweet by anyone who tastes it. Isaiah is suggesting that these people have stopped trusting their own senses about moral reality, and they are choosing to believe whatever is convenient.
The verse does not promise that every confused person will be punished in a particular way or at a particular time. It describes a pattern of living and names the danger it carries. It is a diagnosis, not a timetable.
The Context of Isaiah 5:20
The book of Isaiah is traditionally attributed to the eighth-century prophet Isaiah, who ministered in Jerusalem during the reigns of kings like Uzziah, Jotham, Ahaz and Hezekiah. Chapter 5 belongs to a section of early oracles that critique Judah’s leaders and wealthy citizens for injustice, drunkenness and religious hypocrisy. The audience is the people of Judah in Jerusalem, many of whom considered themselves faithful while their society was crumbling.
The verses just before and after this one sharpen its meaning. Verse 18 speaks of those who drag sin along with ropes of falsehood, and verse 19 quotes those who mock God’s timing and invite him to hurry up and prove himself. Verse 21 turns to those who are “wise in their own eyes,” and verses 22 and 23 describe leaders who drink heavily and take bribes to acquit the guilty. Read this way, verse 20 is not a stray complaint about language. It names the inner mental habit that makes all the other corruption possible: once people trust their own judgment over God’s, they can justify almost anything.
Key Phrases in Isaiah 5:20
Romans 1:18
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness…
(WEB)
Paul describes how people suppress the truth they already know about God, which echoes Isaiah’s picture of people who have lost the ability to see clearly. Reading the two together shows that moral confusion is not new and is rooted in a refusal to honor what God has made known.
Proverbs 14:12
There is a way which seems right to a man, but in the end it leads to death.
(WEB)
This proverb warns that a path can seem right to a person and still lead to death. It fits closely with Isaiah’s concern that people trust their own judgment over God’s wisdom, and it offers a sober counterpart to the deceptive sweetness Isaiah describes.
A Short Prayer From Isaiah 5:20
Lord, you are the one who truly knows what is good and what is evil, and I do not want to rename my choices to make them feel safer than they are. Open my eyes to see where I have called darkness light or bitter sweet. Give me the courage to tell the truth about my own heart, and the humility to receive your correction without hardening against it. Lead me in your light and keep me from trusting my own cleverness above your word. Amen.
