22The eye is the lamp of the body. If your eyes are good, your whole body will be full of light.
23But if your eyes are bad, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness!

The sentence as it lands
“The eye is the lamp of the body. If your eyes are good, your whole body will be full of light. But if your eyes are bad, your whole body will be full of darkness.”
Almost every sermon on this treats it as a warning about what you look at — guard your eyes, watch what you consume. That is a reasonable thing to take from the English, and it is not what the phrase meant.

an evil eye — that is, a stingy one
In Jewish and wider Mediterranean usage, having an “evil eye” meant being grudging with your money. Having a “good” or “single” eye meant being generous. It is a set phrase about the purse, the way English says tight-fisted without anyone picturing a fist.
The idiom is well attested. Proverbs uses the same figure, where the stingy man is literally the man with an evil eye, and Jesus uses it for begrudging a wage in Matthew 20 — which the Berean renders there as “envious”, the other end of the same range.
Your Bible will not show you the phrase here. The Berean translates the sense rather than the words: “if your eyes are good”, “if your eyes are bad”. That is a fair rendering, and it is most of why the idiom is easy to miss.

Setting
Look at what surrounds it
Matthew 6:19–24, read straight through
Before the eye: do not store up treasures on earth, store them in heaven, where your treasure is your heart will be. After the eye: no one can serve two masters — you cannot serve both God and money.
Money on one side, money on the other, and a sentence about eyes in between. Reading the middle as a passage about visual purity requires the surrounding six verses to be a coincidence.

The text
19Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal.
20But store up for yourselves treasures in heaven, where moth and rust do not destroy, and where thieves do not break in and steal.
21For where your treasure is, there your heart will be also.
22The eye is the lamp of the body. If your eyes are good, your whole body will be full of light.
23But if your eyes are bad, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness!
24No one can serve two masters: Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and money.
Matthew 6:19–24 · BSB
Read it as one paragraph rather than three sayings, and watch the subject stay the same.

Now the middle verse fits
A generous eye fills you with light. A grudging one fills you with darkness. And then: you cannot serve both God and money.
It is not a change of subject and never was. What you do with what you have is being described as something that determines whether you are full of light or full of dark — which is a considerably heavier claim than a warning about where you let your gaze land.

What this doesn't mean
This is a lesson about what a phrase meant, not a measure of anyone’s giving. Somebody in debt, out of work, or carrying people on one income is not the grudging eye Jesus described. The idiom is about holding back what you have, not about how much you have.
So take the next card as a question about one decision in front of you, not a verdict on the season you are in.

What did “an evil eye” mean in this idiom?
A superstitious curse cast by a look
Being stingy or grudging with money
Looking at something forbidden
A physical ailment Jesus offers to heal
Stinginess. Which is why the saying sits between treasure on earth and serving mammon — the paragraph never changes subject, and it is our unfamiliarity with the phrase that made it look like it did. The idiom does stretch to begrudging what somebody else has: Matthew 20:15 uses it that way, and the Berean renders it there as “envious”. Both ends are about the hand rather than the eye.

Reflection
What would a generous eye look like in a decision you are facing this month?
Be specific rather than general. A decision, not a disposition.
