The One Sin Yom Kippur Won’t Forgive, and How to Make It Right
Netivyah International
Yom Kippur means “Day of Atonement.” It falls on the 10th day of the Hebrew month of Tishrei, about a week after Rosh Hashanah, and it is the most solemn fast day of the Jewish year.
But here is the part many people miss. Yom Kippur is not a shortcut around repentance. Jewish teaching, and the teaching of Yeshua (Jesus), draw a clear line. Sins against God are confessed to God. Sins against another person must be made right with that person.
When Yom Kippur and Rosh Hashanah fall
Yom Kippur is observed on Tishrei 10. Like Shabbat, it begins at sundown the evening before and ends after nightfall the next day. That is why you will hear it called a 25-hour fast.
Rosh Hashanah begins on Tishrei 1 and is kept for two days. The stretch from Rosh Hashanah through Yom Kippur is called the Ten Days of Repentance, or the Days of Awe. These are days for honest self-examination, prayer, giving, paying debts, returning what belongs to others and asking forgiveness.

If you searched “when is Yom Kippur 2026,” the biblical answer does not change: Tishrei 10. The civil date moves every year because the Jewish calendar follows both the moon and the sun. Check a reliable Jewish calendar for the date and your local sunset time.
Where Yom Kippur comes from in Scripture
The main Torah passage is Leviticus 16. It describes the yearly service of atonement: the high priest, the sin offerings, the blood brought into the Holy of Holies and the goat sent into the wilderness bearing the iniquities of the people.
Leviticus 16:29-30 says:
“And it shall be a statute to you forever that in the seventh month, on the tenth day of the month, you shall afflict yourselves and shall do no work, either the native or the stranger who sojourns among you. For on this day shall atonement be made for you to cleanse you. You shall be clean before the LORD from all your sins.”
Leviticus 23:26-32 repeats the command as a holy convocation, a day of self-denial and complete rest. Numbers 29:7-11 lists the offerings for the day.
So Yom Kippur is not just a custom. It is one of the appointed times (moadim) given in the Torah. With no Temple standing in Jerusalem, the sacrificial service cannot be performed. The day itself remains, and it is still kept as a day of fasting, confession and mercy.
How Yom Kippur is kept in Jewish practice
The Mishnah (Yoma 8:1) names five restrictions for the day: no eating or drinking, no bathing, no anointing with oil, no leather shoes and no marital relations. Work is set aside as on Shabbat. Many wear white as a sign of humility and purity. We explain that custom in White Clothing on Atonement Day.
The evening service opens with Kol Nidre, a solemn declaration about vows. It sets the tone for the whole day: our words matter before God. You can read the prayer in Kol Nidre (All Vows).
Throughout the services, the congregation recites two confessions, Ashamnu (“we have been guilty”) and Al Chet (“for the sin which we have sinned”). These are the traditional Yom Kippur lists of sins. They name things like betraying, robbing, speaking slander, scoffing and hardening the heart. Every line is in the plural. You may not have committed every sin on the list, but you stand with your people before God, and none of us comes alone.
Another prayer heard throughout the season is Avinu Malkeinu: Our Father, Our King. It asks for mercy, not on the basis of our merit, but because God is compassionate.
The one thing Yom Kippur will not do
The Mishnah puts it plainly. In plain English:
“For transgressions between a person and God, Yom Kippur atones; but for transgressions between a person and another, Yom Kippur does not atone until he appeases his fellow.” (Mishnah Yoma 8:9)
That is the heart of the matter. If I sinned against God, I confess to God. If I sinned against my neighbor, I cannot use prayer as a way to avoid my neighbor.
The Talmud (Yoma 87a) goes further. A person who has wronged someone should go and ask forgiveness, and if refused, ask again, up to three times. If the other person still refuses, the one who tried has done his part. He should still wish the other person well.
In practice, this is often thinned out. People send a group message: “If I hurt anyone this year, please forgive me.” It sounds humble, but it usually avoids the actual conversation. The conflict stays where it was.
The instinct behind the custom is right, though. Before we stand before God on the Day of Atonement, we should do everything in our power to stand rightly with our brother or sister.
Yeshua makes it stronger
Yeshua’s teaching in Matthew 5:23-24 is direct:
“So if you are offering your gift at the altar and there remember that your brother has something against you, leave your gift there before the altar and go. First be reconciled to your brother, and then come and offer your gift.”
To us, that can sound like a gentle principle. To the people listening in Galilee, it sounded expensive. Walking from Galilee to the Temple in Jerusalem took several days. If a man remembered at the altar that someone back home had something against him, Yeshua told him to leave his offering, walk home, make peace and then walk back. That meant more days on the road and lost wages, all for one relationship.
Yeshua was not being sentimental. Reconciliation is not an optional extra to worship. It comes first.
Notice also who moves. Not the offended person. You. “If they have a problem with me, they can come to me” is exactly the answer Yeshua rules out.
What this day means for followers of Yeshua
We believe Yeshua is our great High Priest and that His atoning work is complete. The letter to the Hebrews uses the language of the Day of Atonement to describe Him entering the heavenly holy place and securing an eternal redemption (Hebrews 9:11-14).
So why mark Yom Kippur at all?
Because forgiveness from God is not a reason to stop repenting. It is the reason we can. Yom Kippur gives us a yearly appointment with honesty. It exposes the small excuses we have learned to live with. It reminds us that sin is specific, forgiveness is costly and reconciliation is not a private feeling we keep in our own hearts.
We should be living this way all year. Most of us put it off. Yom Kippur is a reset and a deadline, a fixed point on the calendar that says: settle it now.
Paul writes, “Be angry and do not sin; do not let the sun go down on your anger” (Ephesians 4:26). That is Yom Kippur in daily form. Do not let resentment sleep in the house overnight.
Romans 12:18 adds a needed word: “If possible, so far as it depends on you, live peaceably with all.” Some people refuse peace. Some contact would be unsafe. Scripture does not command foolishness. But as far as it depends on us, we pursue peace.
How to ask forgiveness without making it worse
A real apology names the wrong and takes the weight of it. Something like:
“I sinned against you when I said those words. I was wrong. Will you forgive me?”
Or: “I took what was not mine. I have returned it, and I want to repay the loss. Please forgive me.”
Avoid “I’m sorry you felt hurt,” which quietly makes their feelings the problem. Avoid “mistakes were made,” which hides who made them.
Go ready to listen, too. Sometimes we arrive planning to forgive and discover we were the one who caused the trouble. Saying “I forgive him” from a distance can be a way of never finding that out.
If money is involved, repay it. If property is involved, return it. If a lie was told, correct it with the people who heard it. And if a direct conversation does not bring peace, Yeshua gives the next step in Matthew 18:15-16: bring one or two mature believers with you.
The sin of the mouth
Gossip often dresses up as concern, a prayer request or “just processing.” Much of the time it is simply talking about someone’s fault with a third person instead of with the person involved. Unresolved talk like this has split many congregations.
The Torah says, “You shall not go around as a slanderer among your people” (Leviticus 19:16). Two verses later: “You shall love your neighbor as yourself” (Leviticus 19:18). The two commands sit side by side for a reason.
Yom Kippur calls us to confess sins with our mouths. It also calls us to stop sinning with them.
A simple way to mark Yom Kippur at home
You do not need to recreate a synagogue service. Keep it simple and sincere.
The afternoon before, gather as a family and read Leviticus 16:29-34, Matthew 5:23-24 and 1 John 1:8-9. Then give everyone quiet time with two questions:
- Is there anything I need to confess to God?
- Is there anyone I need to contact and make things right with?
If your children are old enough, teach them to apologize plainly: name the wrong, ask forgiveness and make it right where they can. That is discipleship.
Eat a good meal together before sundown, then keep the day quiet. If your health allows, fast. If it does not, choose another form of self-denial and give the hours to prayer and Scripture. When the day ends at nightfall, break the fast together and thank God for His mercy.
A Yom Kippur prayer for forgiveness
Father in heaven, our Father and our King, we come before You with no excuses. Search us and show us the sins we have hidden, softened or renamed. Forgive us through the mercy You have given in Yeshua the Messiah. Give us courage to go to anyone we have wronged, to tell the truth, to repay what we owe and to seek peace without pride. Keep our mouths from gossip and our hearts from bitterness. Teach us to forgive as we have been forgiven. Amen.
If one name came to mind while you were reading, do not push it aside. Write it down tonight, and decide when you will call.

How do I ask forgiveness before Yom Kippur?
Go to the person directly if it is wise and safe. Name what you did, take responsibility without excuses, ask forgiveness and make restitution where needed. Rabbinic tradition says to ask up to three times. If that still fails, Matthew 18:15-16 says to bring one or two mature believers.
