New Moon

The new moon stands in the UPDV as the lunar boundary that opens each month, and as a recurring liturgical day on which Israel blows trumpets, brings burnt-offerings, and sits in royal company. Its rhythm runs the length of the canon — from the trumpet-call set in the wilderness, to the post-exile altar's monthly rota, to the prophetic complaint that the rite has become a wearying burden, to a Hellenistic-era apologist's complaint that the cycle is being kept at all.

The Founding Trumpet-Call

The Sinai legislation installs the new moon as one of three trumpet-blowing occasions over Israel's offerings: "Also in the day of your⁺ gladness, and in your⁺ set feasts, and in the beginnings of your⁺ months, you⁺ will blow the trumpets over your⁺ burnt-offerings, and over the sacrifices of your⁺ peace-offerings; and they will be to you⁺ for a memorial before your⁺ God: I am Yahweh your⁺ God" (Nu 10:10). The month-beginning stands beside gladness-days and the set feasts, and the trumpet-blast is laid down as a memorial sounded over altar-offerings.

Asaph's psalm fixes the same trumpet at both ends of the lunar cycle: "Blow the trumpet at the new moon, At the full moon, on our feast-day" (Ps 81:3). The new moon and the full moon together bracket the month between two trumpet-marked stations of the moon.

The Monthly Burnt-Offering

Numbers 28 sets out the inventory in detail. The base offering is laid down first: "And in the beginnings of your⁺ months you⁺ will offer a burnt-offering to Yahweh: two young bullocks, and one ram, seven he-lambs a year old without blemish" (Nu 28:11). The accompanying meal- and drink-offerings follow in measured proportion — "three tenth parts [of an ephah] of fine flour for a meal-offering, mingled with oil, for each bull; and two tenth parts of fine flour for a meal-offering, mingled with oil, for the one ram; and a tenth part of fine flour mingled with oil for a meal-offering to every lamb; for a burnt-offering of a sweet savor, an offering made by fire to Yahweh" (Nu 28:12-13). The drinks are paired beast-by-beast: "their drink-offerings will be half a hin of wine for a bull, and the third part of a hin for the ram, and the fourth part of a hin for a lamb: this is the burnt-offering of every month throughout the months of the year" (Nu 28:14). A sin-offering closes the list: "And one he-goat for a sin-offering to Yahweh; it will be offered besides the continual burnt-offering, and the drink-offering of it" (Nu 28:15). The whole inventory is set as the monthly cycle through the year, stacked above the continual daily burnt-offering rather than replacing it.

The Sabbath-and-Feast Triad

Across the historical books, the new moon is named with the Sabbath and the appointed feasts as a fixed three-occasion offering-list. David's Levite-duty summary fastens "all burnt-offerings to Yahweh, on the Sabbaths, on the new moons, and on the set feasts, in number according to the ordinance concerning them, continually before Yahweh" (1Ch 23:31). Hezekiah's reform repeats the pattern, with the king's own portion underwriting the offerings: "[He appointed] also the king's portion of his substance for the burnt-offerings, [to wit,] for the morning and evening burnt-offerings, and the burnt-offerings for the Sabbaths, and for the new moons, and for the set feasts, as it is written in the law of Yahweh" (2Ch 31:3). When the post-exile altar is re-founded under Ezra, the same triad reappears — "afterward the continual burnt-offering, and [the offerings] of the new moons, and of all the set feasts of Yahweh that were consecrated, and of everyone who willingly offered a freewill-offering to Yahweh" (Ezr 3:5) — the new moon stacked between the twice-daily continual offering and the set-feast services as the second layer of the restored rota.

The King's Table

The day carries a social and royal-court obligation alongside its altar-rite. David tells Jonathan: "Look, tomorrow is the new moon, and I should not fail to sit with the king at meat: but let me go, that I may hide myself in the field until the evening" (1Sa 20:5). The new-moon meal is a standing engagement at Saul's table — David's absence from it is significant precisely because attendance is expected.

Trade Suspended

Amos catches a complaint that fits the day from the other side. The grain-merchants chafe at the calendar: "saying, When will the new moon be gone, that we may sell grain? And the Sabbath, that we may set forth wheat, making the ephah small, and the shekel great, and dealing falsely with balances of deceit" (Am 8:5). Trade is paused on the new moon as it is on the Sabbath; the merchants resent the pause and wait it out only so they can resume their cheating. The day is exhibited here as a working trade-suspension that constrains the marketplace.

Prophetic Rejection

The eighth-century prophets put the new moon under judgment when its keeping is detached from justice. Isaiah hears Yahweh disown the calendar: "Your new moons and your⁺ appointed feasts my [Speech] has rejected; they are a trouble to me; I am weary of bearing them" (Is 1:14). Hosea pronounces the same cessation against the addressed wife: "I will also cause all her mirth to cease, her feasts, her new moons, and her Sabbaths, and all her solemn assemblies" (Ho 2:11). The new moon sits inside both lists as one named festal-day among the broader cycle — rejected in Isaiah as a wearying burden, silenced in Hosea among the wife's whole calendar of mirth.

Hellenistic-Era Protection

The rhythm carried forward into post-biblical practice. Demetrius's concession-letter in 1 Maccabees names the new moons in a kingdom-wide list of protected days: "And I will that all the feasts, and the Sabbaths, and the new moons, and the days appointed, and three days before the solemn day, and three days after the solemn day, be all days of immunity and freedom, for all the Jews who are in my kingdom" (1Ma 10:34). The new moon appears here as one item in a six-fold festal-and-buffer calendar Demetrius offers to make legally immune from royal levy.

Lunar Timekeeping in Sirach

The sage of Ben Sira frames the same rhythm as a function of the moon itself. The festival-fixing is keyed to the lunar cycle: "By her festivals and the appointed times [are fixed], A light that wanes when she has come to the full" (Sir 43:7). The renewal that opens each new moon is folded into the moon's own self-renewing office: "Month by month she renews herself, How wonderful [is she] in her changing! A beacon for the hosts on high, Paving the firmament with her shining" (Sir 43:8). The new month's arrival is exhibited here as the moon's own monthly self-renewal, the wax-and-wane cycle that anchors the festival calendar.

A Critique from the Apologist

The Epistle to Diognetus turns the same lunar-festal pattern into a complaint. Of those who keep the calendar, the writer says: "And then they attend to stars and moon, observing months and days. They distribute God's dispensations and the changes of seasons according to their own impulses, allotting some days to feasts and others to mourning. Who would count this as an example of godliness? Is it not much more [an example] of folly?" (Gr 4:5). Moon-watching for festival-allotment, in this register, is judged folly rather than godliness — a self-directed carving-up of the year, set against the apologist's preferred posture toward divine dispensations.
