Revelation 1:10-13 I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like the sound of a trumpet, 11 saying, “Write in a book what you see, and send it to the seven churches: to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
Many derive from this expression, the later much used idea of this expression for Sunday, or the first day of the week. The equating of this phrase with Sunday is once again based upon later Apocryphal writings such as The Gospel of Peter, where such language is clearly used of Sunday, or other early Christian Fathers literature.
The actual Greek phrase, ἐν τῇ κυριακῇ ἡμέρᾳ, is different than the typical prophetic expression Day of the LORD, ̔ημέρα τοῦ κυρίου which is found throughout the Septuagint and the Apostolic Writings to translate the Hebrew "Day of ADONAI." The main reason for understanding this phrase as "The Day of the LORD," is due to the internal evidence that John is indeed describing the Day of ADONAI, the Day of Wrath upon this earth. Chapters 4-22 deal with these concepts and prophecies.
Revelation 6:15- 17 Then the kings of the earth and the great men and the commanders and the rich and the strong and every slave and free man hid themselves in the caves and among the rocks of the mountains; 16 and they said to the mountains and to the rocks, “Fall on us and hide us from the presence of Him who sits on the throne, and from the wrath of the Lamb; 17 for the great day of their wrath has come, and who is able to stand?”
