Psalm 2:8
7 The king says, “I will announce the Lord’s decree. He said to me: ‘You are my son. This very day I have become your father. 8 Ask me, and I will give you the nations as your inheritance, the ends of the earth as your personal property. 9 You will break them with an iron scepter; you will smash them like a potter’s jar.’” 10 So now, you kings, do what is wise; you rulers of the earth, submit to correction.
Revelation 2:26
25 However, hold on to what you have until I come. 26 And to the one who conquers and who continues in my deeds until the end, I will give him authority over the nations— 27 he will rule them with an iron rod, and like clay jars he will break them to pieces, 28 just as I have received the right to rule from my Father—and I will give him the morning star.
Notes and References
"... At the end of each one of these letters, after the exalted Christ has reviewed the particular situation of the church and set out what he requires, a promise to the ‘one who conquers’ is put before the church. In the case of the letter to the church in Thyatira (2.18-29), this Uberwinderspruch (overcomer saying) is shaped by a clear appeal to Psalm 2.8-9. The ‘Son of God’, which is the self-presentation found at the beginning of the letter, promises to ‘the one who conquers and does my works to the end’ that ‘I will give him authority over the nations’. The words give the cue for Psalm 2, and this leads to a grammatically adjusted allusion to Psalm 2.9 ..."
