Leviticus 23:24

23:24 “Tell the Israelites, ‘In the seventh month, on the first day of the month, you must have a complete rest, a memorial announced by loud horn blasts, ¹  a holy assembly.

Leviticus 23:39

23:39 “‘On ²  the fifteenth day of the seventh month, when you gather in the produce of the land, you must celebrate a pilgrim festival of the Lord for seven days. On the first day is a complete rest and on the eighth day is complete rest.

Numbers 10:10

10:10 “Also in the time when you rejoice, such as ³  on your appointed festivals or ⁴  at the beginnings of your months, you must blow with your trumpets over your burnt offerings and over the sacrifices of your peace offerings, so that they may ⁵  become ⁶  a memorial for you before your God: I am the Lord your God.”

Psalms 81:1-4

Psalm 81 ⁷ 

For the music director; according to the gittith style; ⁸  by Asaph.

81:1 Shout for joy to God, our source of strength!

Shout out to the God of Jacob!

81:2 Sing ⁹  a song and play the tambourine,

the pleasant sounding harp, and the ten-stringed instrument!

81:3 Sound the ram’s horn on the day of the new moon, ¹⁰ 

and on the day of the full moon when our festival begins. ¹¹ 

81:4 For observing the festival is a requirement for Israel; ¹² 

it is an ordinance given by the God of Jacob.

Isaiah 1:13-14

1:13 Do not bring any more meaningless ¹³  offerings;

I consider your incense detestable! ¹⁴ 

You observe new moon festivals, Sabbaths, and convocations,

but I cannot tolerate sin-stained celebrations! ¹⁵ 

1:14 I hate your new moon festivals and assemblies;

they are a burden

that I am tired of carrying.

[23:24]  ¹ tn Heb “a memorial of loud blasts.” Although the term for “horn” does not occur here, allowing for the possibility that vocal “shouts” of acclamation are envisioned (see P. J. Budd, Leviticus [NCBC], 325), the “blast” of the shofar (a trumpet made from a ram’s “horn”) is most likely what is intended. On this occasion, the loud blasts on the horn announced the coming of the new year on the first day of the seventh month (see the explanations in J. E. Hartley, Leviticus [WBC], 387, and B. A. Levine, Leviticus [JPSTC], 160).

[23:39]  ² tn Heb “Surely on the fifteenth day.” The Hebrew adverbial particle אַךְ (’akh) is left untranslated by most recent English versions; however, cf. NASB “On exactly the fifteenth day.”

[10:10]  ³ tn The conjunction may be taken as explicative or epexegetical, and so rendered “namely; even; that is,” or it may be taken as emphatic conjunction, and translated “especially.”

[10:10]  ⁴ tn The vav (ו) is taken here in its alternative use and translated “or.”

[10:10]  ⁵ tn The form is the perfect tense with vav (ו) consecutive. After the instruction imperfects, this form could be given the same nuance, or more likely, subordinated as a purpose or result clause.

[10:10]  ⁶ tn The verb “to be” (הָיָה, hayah) has the meaning “to become” when followed by the preposition lamed (ל).

[81:1]  ⁷ sn Psalm 81. The psalmist calls God’s people to assemble for a festival and then proclaims God’s message to them. The divine speech (vv. 6-16) recalls how God delivered the people from Egypt, reminds Israel of their rebellious past, expresses God’s desire for his people to obey him, and promises divine protection in exchange for obedience.

[81:1]  ⁸ tn The precise meaning of the Hebrew term הַגִּתִּית (haggittit) is uncertain; it probably refers to a musical style or instrument. See the superscription to Ps 8.

[81:2]  ⁹ tn Heb “lift up.”

[81:3]  ¹⁰ tn Heb “at the new moon.”

[81:3]  ¹¹ tn Heb “at the full moon on the day of our festival.” The Hebrew word כֶּסֶה (keseh) is an alternate spelling of כֶּסֶא (kese’, “full moon”).

[81:4]  ¹² tn Heb “because a statute for Israel [is] it.”

[1:13]  ¹³ tn Or “worthless” (NASB, NCV, CEV); KJV, ASV “vain.”

[1:13]  ¹⁴ sn Notice some of the other practices that Yahweh regards as “detestable”: homosexuality (Lev 18:22-30; 20:13), idolatry (Deut 7:25; 13:15), human sacrifice (Deut 12:31), eating ritually unclean animals (Deut 14:3-8), sacrificing defective animals (Deut 17:1), engaging in occult activities (Deut 18:9-14), and practicing ritual prostitution (1 Kgs 14:23).

[1:13]  ¹⁵ tn Heb “sin and assembly” (these two nouns probably represent a hendiadys). The point is that their attempts at worship are unacceptable to God because the people’s everyday actions in the socio-economic realm prove they have no genuine devotion to God (see vv. 16-17).
