Psalm 81:3, “Blow the trumpet at the new moon, at the full moon, on our feast day,” is a concise command embedded within a psalm that calls for joyous worship and remembrance of God’s deliverance. To fully appreciate its meaning, a scholarly approach requires an examination of its historical context, the specific Hebrew terminology used, and its theological implications within ancient Israelite cultic practice. This verse is not merely an instruction but a window into the vibrant liturgical life of Israel and the profound connection between divine commands and national identity.
The Liturgical Command in “81/3”: Hebrew Terminology and Feast Days
The injunction in Psalm 81:3, often referred to by the shorthand “81/3”, mandates the blowing of the shofar (a ram’s horn) or a trumpet at specific times: the “new moon” (chodesh) and the “full moon” (keseh), which is identified as “our feast day” (chag). The new moon marked the beginning of each month and often involved special sacrifices and celebrations (Numbers 10:10, 28:11-15). The “full moon” here almost certainly refers to the Feast of Tabernacles (Sukkot), which began on the 15th day of the seventh month, a time when the moon would be full (Leviticus 23:34). It is also possible, though less certain for this specific verse, that it could encompass Rosh Hashanah (Feast of Trumpets), which falls on the new moon of the seventh month and is characterized by trumpet blasts. The use of the shofar was deeply symbolic, serving to announce sacred times, summon the assembly, and even to herald God’s presence or coming judgment.
The pairing of “new moon” and “full moon” suggests a comprehensive cycle of national celebration and remembrance. The phrase “our feast day” specifies that the full moon celebration was a major pilgrimage festival, a chag, highlighting its communal and covenantal significance. This command underscores the importance of calendrical observance in maintaining Israel’s relationship with Yahweh and commemorating His historical interventions.
Contextualizing Psalm 81:3 within the Broader Psalm and Israelite Worship
Psalm 81 itself is identified as an Asaphic psalm, often associated with temple worship and prophetic instruction. The verses immediately preceding Psalm 81:3 (“Sing aloud to God our strength; shout for joy to the God of Jacob! Raise a song; sound the tambourine, the sweet lyre with the harp.”) set a tone of exuberant praise. This praise is intrinsically linked to the command to sound the trumpets, indicating that these observances were not merely ritualistic but were expressions of heartfelt joy and gratitude for God’s past deliverance.
The psalm proceeds to recount God’s bringing Israel out of Egypt and lament their disobedience in the wilderness. Thus, Psalm 81:3 serves as a call to remember and re-engage with the covenant through mandated celebrations. These feasts were not only agricultural festivals but powerful theological reminders of God’s redemptive history. The blowing of the trumpet marked these sacred times, calling the people to assembly, to remember, and to renew their commitment to the God who delivered them from oppression.
