Few prophetic phrases are quoted more often than Jesus’ words in Matthew 24:36: “Now concerning that day and hour no one knows.” Some believers use this verse to discourage any study of Bible prophecy, as though Jesus meant, “Do not ask, do not search, do not discern.” Others move in the opposite direction and claim Jesus was giving a hidden Jewish clue to the Feast of Trumpets, also called Yom Teruah and later associated with Rosh Hashanah. According to that view, because the feast involved the sighting of the new moon, Jesus’ phrase supposedly meant, “You cannot know the exact day or hour, but you can know the feast window.”
That claim is attractive because it sounds ancient, Jewish, and prophetic. But the Christian must ask a more basic question: does the text actually say that? A theory can sound biblical while still being imported into Scripture rather than drawn from Scripture. The issue is not whether Israel’s feasts are meaningful. They are. The issue is whether Jesus, in Matthew 24:36-44, was secretly identifying the timing of the rapture, or plainly teaching watchfulness, readiness, and the unknowability of the hour. Bible Gateway’s CSB text shows that Jesus’ emphasis in this passage is not calendar calculation but alertness, because “the Son of Man is coming at an hour you do not expect.”
The Feast of Trumpets is unquestionably biblical. Leviticus 23:23-25 commands Israel to observe a day of rest, trumpet blasts, and sacred assembly on the first day of the seventh month. It is also true that ancient Jewish calendar practice involved the observation of the new moon. Sefaria’s summary of Mishnah Rosh Hashanah notes that the tractate discusses the sanctifying of a new month through witnesses who testified before the rabbinic court that they had seen the new moon. (Sefaria) That supports the historical point that lunar observation mattered. It does not, however, prove that “no one knows the day or hour” was a recognized title, idiom, or coded phrase for the Feast of Trumpets in Jesus’ day.
That distinction matters. A feast can involve lunar observation without Jesus’ statement becoming a veiled feast reference. In Matthew 24:36, Jesus does not mention trumpets, the new moon, Rosh Hashanah, Yom Teruah, or witnesses. He says plainly that no one knows that day and hour except the Father. Then He immediately grounds the point in the days of Noah. People were eating, drinking, marrying, and giving in marriage until judgment arrived suddenly (Matthew 24:37-39). The emphasis is moral and spiritual, not calendrical. What assumptions underlie our eagerness to turn a warning into a puzzle?
Jesus’ command is direct: “Therefore be alert, since you don’t know what day your Lord is coming” (Matthew 24:42). He adds, “This is why you are also to be ready, because the Son of Man is coming at an hour you do not expect” (Matthew 24:44). If the point were to identify a yearly prophetic window, the logic would weaken. Jesus does not say, “Watch the autumn feast.” He says, “Be ready.” The blessed hope is not a date hidden inside a festival pattern; it is Christ Himself.
This harmonizes with Paul’s teaching about the church’s expectation. In Titus 2:13, believers are described as waiting for “the blessed hope, the appearing of the glory of our great God and Savior, Jesus Christ.” In 1 Thessalonians 4:16-18, Paul says the Lord Himself will descend from heaven, the dead in Christ will rise first, and living believers will be “caught up together with them in the clouds to meet the Lord in the air.” He then says, “Therefore encourage one another with these words.” The focus is not Antichrist-watching, seal-counting, or feast-window speculation. The focus is the Lord Himself.
This is why the doctrine of imminency is so pastorally important. In a pre-tribulation, dispensational reading, the rapture is signless and imminent, while the visible second coming of Christ to earth is preceded by identifiable tribulation signs. Matthew 24 earlier speaks of wars, persecution, the abomination of desolation, cosmic disturbances, and the Son of Man coming with power and great glory (Matthew 24:4-31). By contrast, Paul’s comfort to the church in 1 Thessalonians 4 is not framed as endurance through Daniel’s seventieth week but as expectation of Christ’s sudden gathering of His people. Ice, drawing from Walvoord and Brindle, argues that the absence of preceding signs in passages such as Titus 2:13 and 1 Thessalonians 4:18 strongly supports imminency as a comfort and exhortation for the church.
This does not mean Christians escape all suffering. Jesus said plainly, “You will have suffering in this world” (John 16:33). The church has endured persecution, martyrdom, deception, and spiritual warfare throughout this age. But suffering in the present world is not the same as being appointed to the eschatological wrath of the Day of the Lord. Paul says, “For God did not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ” (1 Thessalonians 5:9). That promise should produce humility, holiness, courage, and gospel urgency, not laziness or escapism.
Matthew 24 also contains the well-known statement that one person is taken and another left (Matthew 24:40-41). Careful readers recognize that sincere interpreters differ over whether “taken” in that immediate context refers to judgment, as in Noah’s day, or to sudden removal in a way that harmonizes with rapture language. Yet the central point remains clear either way: separation will come suddenly, and readiness cannot be borrowed at the last minute. Jesus’ warning leaves no room for spiritual carelessness.
There is a serious pastoral danger in turning the rapture into an annual guessing game. Every year, as the fall feasts approach, some believers are stirred into heightened expectations around a specific window. When the window passes, disappointment follows. Skeptics mock. Sincere believers become confused or weary. The problem is not prophetic hope; the problem is prophetic sensationalism. The biblical doctrine of imminency does not mean Jesus must come on our preferred calendar day. It means nothing must happen before He comes. We are not waiting for a hidden idiom to be decoded. We are waiting for the Lord.
The gospel must remain central. Being ready for Christ is not achieved by joining a church, improving one’s moral record, or becoming religious. Paul defines the gospel in 1 Corinthians 15:1-4: Christ died for our sins according to the Scriptures, He was buried, and He was raised on the third day according to the Scriptures. Salvation is received by grace through faith, “not from works, so that no one can boast” (Ephesians 2:8-9). The believer is sealed with the Holy Spirit of promise (Ephesians 1:13-14). That is our confidence.
So, did Jesus hide a Rosh Hashanah clue in Matthew 24:36? The stronger answer is no. He gave a loving warning. Be alert. Be ready. Do not mistake curiosity for watchfulness or speculation for discernment. The Bridegroom may come at an hour we do not expect. Are we looking for dates, or are we looking for Christ? Are we feeding on theories, or are we walking in holiness, gospel urgency, and sober hope? The world will continue eating, drinking, building, buying, mocking, and sleeping until the moment God interrupts history. The church must not sleep with it.
Our hope is not in a calendar code. Our hope is Jesus Christ, crucified, risen, coming again, and faithful to every promise He has made.
