Psalm 2 is the second psalm of the Book of Psalms, beginning in English in the King James Version: "Why do the heathen rage". In Latin, it is known as "Quare fremuerunt gentes". Psalm 2 does not identify its author with a superscription, but Acts 4:24–26 in the New Testament attributes it to David. According to the Talmud, Psalm 2 is a continuation of Psalm 1.

Revelation 2 is the second chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible. The book is traditionally attributed to John the Apostle, but the precise identity of the author remains a point of academic debate. This chapter contains messages to churches of Ephesus, Smyrna, Pergamum and Thyatira, four of the seven churches of Asia located in modern-day Turkey, with messages for the other three churches appearing in chapter 3.
