Feast of Trumpets: Yom Teruah

Overview

Leviticus 23:23-25 commands Israel to keep a day in the seventh month marked by teruah — usually translated "trumpets." This study works through what the text actually says before asking what it points toward, and checks a popular typological argument (that this feast previews the rapture) against what's actually stated versus inferred.

Historical context

"Speak to the people of Israel, saying, In the seventh month, on the first day of the month, you shall observe a day of solemn rest, a memorial proclaimed with blast of trumpets, a holy convocation. You shall not do any ordinary work, and you shall present a food offering to the LORD." (Leviticus 23:23-25, ESV)

The text itself names this day Yom Teruah — it does not call it "Rosh Hashanah" ("head of the year") or "Feast of Trumpets." Both of those are later traditional names, not the Torah's own vocabulary, and it's worth keeping the distinction: "Rosh Hashanah" reflects a civil-calendar new-year framing (Tishrei 1) that sits alongside, not in place of, the religious calendar's own new year at Nisan 1 (Exodus 12:2 — the month of the Exodus is explicitly made "the first month of the year" for Israel's religious calendar, which is why the seventh month carries a name about a "memorial," not "new year").

The day's starting moment depended on testimony, not calculation: a new month began when witnesses sighted the new moon and reported it, a detail that matters for why this feast in particular came to be associated with an unknown starting hour (see below). Mishnah Rosh Hashanah 4:4 (Sefaria Community Translation, CC0) preserves the actual procedure: witnesses were originally accepted for testimony all day, but after they once arrived late enough to disrupt the evening service, the cutoff moved to the afternoon — with a further adjustment after the Temple's destruction in 70 AD extending the cutoff back to all day. This is later rabbinic material (the Mishnah was redacted around 200 AD), so it documents developed practice, not necessarily the exact procedure in Moses's own day — but the underlying mechanism (new month = witnessed, not calculated) is old and explains a real feature of the text: this is the one appointed time in Leviticus 23 whose exact start Israel did not fully control in advance.

Literary context

Leviticus 23 lists Israel's appointed feasts as one continuous unit, not a miscellany: Passover and Unleavened Bread and Firstfruits cluster in the first month, Weeks (Shavuot) falls fifty days later, and then Trumpets, the Day of Atonement, and Tabernacles cluster in the seventh month. Trumpets is the first of the three fall feasts — it opens that second cluster rather than standing alone, sitting between the spring harvest festivals and the Day of Atonement ten days later. The governing point of Leviticus 23 as a whole: this is a fixed liturgical calendar structuring Israel's entire year around what God has done and will do, not an assortment of unrelated holy days.

Word study: teruah

This is the word the entire feast is named for, and it's worth being precise about what it actually means — the payoff is immediate.

תְּרוּעָה (teruah, H8643), from the root רוּעַ (ruaʿ, H8643's TWOT root, #2135), glossed by TWOT as "raise a shout." Concordancing the word directly against bible-text.db turns up its real range: a war-cry or alarm (Amos 1:14, 2:2; Ezekiel 21:27), a shout at God's presence — the ark's arrival in camp, the ark entering Jerusalem (1 Samuel 4:5-6; 2 Samuel 6:15), and a shout of joy at the temple's foundation being laid (Ezra 3:11-13). The word itself is about the sound — a shout, alarm, or joyful cry — not specifically "a trumpet."

Every major English translation (KJV, ASV, WEB, ESV) renders it "trumpets" or "blowing of trumpets." That's a defensible choice — the shofar was the near-universal means of producing a teruah in a worship setting — but it's worth naming plainly: the translation obscures that the Hebrew text doesn't actually say "trumpet." It says "shout" or "alarm," and instrument-based ways of making that sound are the means, not the word's own meaning. This is the kind of gap the develop-bible-study skill's word-study step exists to catch — a popular understanding built on the English gloss rather than the Hebrew range.

Numbers 10:1-10 confirms teruah is a specific signal pattern, not just any loud noise: blown on the same silver trumpets as tekiah (a long blast, for gathering the assembly), teruah was the short, staccato pattern that signaled the camp to break and march. This tekiah/teruah distinction is the root of the shofar sequence still used today — Mishnah Rosh Hashanah 4:9 describes a three-part tekiah-teruah-tekiah pattern sounded three times through the liturgy, verified directly against the primary text rather than a secondhand description.

One more term worth noting: זִכָּרוֹן (zikkaron, "memorial," H2146) is paired with teruah in the verse itself — "a memorial of teruah" — which directly grounds the traditional name Yom HaZikkaron (Day of Remembrance) in the text's own vocabulary, unlike "Rosh Hashanah."

Genre lens: ceremonial law

Leviticus 23:23-25 is ceremonial law — a fixed calendar observance, not a moral command or a civil statute. Per the develop-bible-study skill's own question for this genre: what does the statute reveal about God's character even where the rule doesn't carry over? Here, that a day built entirely around sound and alertness, with no fixed advance-known hour, teaches a posture: watching and readiness rather than passive calendar-following. That the specific new-moon-witness mechanics don't bind the church doesn't remove that underlying pattern — the same distinction the skill applies elsewhere (a ceremonial detail can be culturally bound while still illustrating something that transcends it).

The trumpets typology: what's stated, what's inferred

A popular teaching (well laid out in Eddie Chumney, The Seven Festivals of the Messiah, ch. "Rosh HaShanah: The Head of the Year") connects three biblical uses of "trumpet" to three of the appointed feasts: a "first trump" at Sinai when the Torah was given (Exodus 19:19, associated with Shavuot), a "last trump" identified with 1 Corinthians 15:51-53's resurrection/rapture trumpet (associated with Rosh Hashanah/Yom Teruah), and a "great trump" identified with Matthew 24:30-31's gathering at Christ's return (associated with Yom Kippur).

Worth being precise about what this argument actually rests on: neither 1 Corinthians 15 nor Matthew 24 names Rosh Hashanah or Yom Kippur. Paul writes "at the last trumpet" (1 Corinthians 15:52, ESV) without dating it to any feast; Jesus speaks of "a great sound of a trumpet" (Matthew 24:31) — WEB's more literal rendering — without naming Yom Kippur either. The connection is built by combining the NT's trumpet language with the rabbinic tradition's own multi-part shofar terminology, then matching them up. That's a real, traceable argument — not an arbitrary one — but it's typological reasoning from shared vocabulary, not something either NT text states outright. Treat it the way this skill treats any argument built from inference rather than explicit statement: worth presenting, not worth asserting as settled.

On the "no one knows the day or hour" connection: Matthew 24:36 uses that exact uncertainty, and it does parallel Yom Teruah's witness-dependent start (see Historical Context above). The earlier draft of this study also asked whether this connects to the "two witnesses" of Revelation 11. Having checked Chumney's book specifically for this: it does not draw that connection anywhere in its Trumpets/Rosh Hashanah material. The two "two-witness" ideas — new-moon sighting testimony and Revelation's two end-times witnesses — appear to be separate motifs that happen to share the number two, not a connection any source consulted here actually makes. Worth investigating further if there's a specific source for it, but it shouldn't be assumed.

Theological principle

Yom Teruah is fundamentally a summons to attention before God, marked by sound rather than by rest, fasting, or feasting the way the other appointed times are. It's the one feast whose starting moment Israel itself did not fully control in advance — built on watching and testimony, not a fixed calculation. That pattern (a call to wake, watch, and be ready) recurs independent of any NT-trumpet-typology argument: Joel 2:1 uses the same call-to-attention shofar language as a summons to repentance, not a rapture reference.

Application

  • What's tied to the original setting: the specific new-moon witness procedure and the rabbinic liturgical order for sounding the shofar (Mishnah Rosh Hashanah 4) are Israel's own calendar-keeping practice, not something the New Testament requires of the church.
  • What transcends it: the pattern of a call to attention and readiness, met with watching rather than passive certainty about timing, shows up as a real biblical theme independent of whether the trumpets-typology argument above is right.
  • Where to hold loosely: the specific three-trumpets scheme (first/last/great) is one teacher's synthesis of shared vocabulary, not a claim either 1 Corinthians 15 or Matthew 24 makes explicitly. It's fine to find it suggestive without treating it as established exegesis.

Discussion questions

  1. Every English translation renders teruah as "trumpets," but the word itself means "shout" or "alarm." Does knowing that change how you read Leviticus 23:24, or does the instrument-based translation capture the point well enough regardless?
  2. The chapter's own three-fall-feasts structure (Trumpets, then Atonement ten days later, then Tabernacles) puts Trumpets first in a sequence. What do you make of a feast about "readiness" preceding one about atonement?
  3. Walk through the trumpets-typology argument in this study's own terms: what does 1 Corinthians 15:51-53 actually say, and what has to be added to connect it to Rosh Hashanah specifically?
  4. Where else in Scripture does a shofar or teruah-type sound function as a call to watchfulness rather than an instrument of celebration (see Joel 2:1, Ezekiel 33:3-6)? What does that pattern suggest about the theme this feast is teaching?
