The word "
κυριακη" (translit. "kuriake") is an Adjective - Dative - Singular - Feminine. This means it is being used as a 'possessive' ("of", see 1 Corinthians 11:20, "the Lord's supper"), which means the "day" in context belongs to "the Lord". It is literally "the Lord's (belonging to) day". This means, that the "day" in context is uniquely "the Lord's" out of all the 7 days of the week, for the day under consideration is that which exists within the week, as a day which repeats weekly. This is extremely important, as those who incorrectly assume it to mean "the first [day] of the week" in lieu of Jesus' resurrection, cannot get a weekly occurrence out of a one-time event, in fulfilment of typology of the Firstfruit/Wavesheaf in Leviticus 23:9-14, as made known in 1 Corinthians 15:20,23..
This is not as the phrase "day of the Lord" (ἡμέρα κυρίου) which is written in the genitive masculine case (see 2 Peter 3:10, etc, and also so called septuaginta uses).
In Latin, we see it similarly used in Exodus 20 (Latin is without the definite article, as Latin does not use definite articles):
Rev 1:10 fui in spiritu in dominica die et audivi post me vocem magnam tamquam tubae
Exo 20:8 memento ut diem sabbati sanctifices
Exo 20:9 sex diebus operaberis et facies omnia opera tua
Exo 20:10 septimo autem die sabbati Domini Dei tui non facies omne opus tu et filius tuus et filia tua servus tuus et ancilla tua iumentum tuum et advena qui est intra portas tuas
Exo 20:11 sex enim diebus fecit Dominus caelum et terram et mare et omnia quae in eis sunt et requievit in die septimo idcirco benedixit Dominus diei sabbati et sanctificavit eum
Which is akin to Genesis' "God's day":
Gen 2:1 igitur perfecti sunt caeli et terra et omnis ornatus eorum
Gen 2:2 conplevitque Deus die septimo opus suum quod fecerat et requievit die septimo ab universo opere quod patrarat
Gen 2:3 et benedixit diei septimo et sanctificavit illum quia in ipso cessaverat ab omni opere suo quod creavit Deus ut faceret
Whereas the differing apocalyptic day, "the day of the Lord" in Latin is "dies Domini" as in Zephaniah 1:14:
Zep 1:14 iuxta est dies Domini magnus iuxta et velox nimis vox diei Domini amara tribulabitur ibi fortis
In Isaiah 58:13, we read of a "day" that "the Lord" specifically calls "my day":
Isa 58:13 If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
In many translations of Isaiah 58:13 we read that the 7th day, the sabbath of the Lord, is said to be "the Lord's holy day", with the word holy being another adjective, while the "Lord's" is possessive. -
/Isaiah 58:13 - Bible Gateway
Thus when reading Isaiah 58:13 with simple pronoun substitution, it would read
"... the ... [Lord's] day ...", just as it does in Exodus 20:8-11.
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
In Genesis we see why this day is uniquely "Gods'", or "the Lord's" day, for in it God rested. This is the reason Jesus could say:
Mat 12:8 For the Son of man is Lord even of the sabbath day.
For in that He created in Genesis, and rested, Colossians 1:16.
Further, we can see some honest persons, among the many commentators that like to simply assume their apriori into the text, or to place future definition back into the text, from non-scriptural materials.
Peter Pett's commentary makes this accurate note:
"... Sunday is not called ‘the Lord’s day’ (he kyriake hemera) anywhere in Scripture ..."
.
Dr. Thomas Constable likewise states the same truth:
"... The New Testament writers never called Sunday the Lord"s day elsewhere in Scripture. ..."
.
Richard Chenevix Trench has stated on record, and accurately that:
"... “Some have assumed, from this passage, that ἡμέρα κυριακή was a designation of Sunday already familiar among Christians. This, however, seems a mistake ..."
.
Likewise, Foy E Wallace states:
"... It is not a reference to the first day of the week ..."
