^2:27 that one ‘will rule them with an iron scepter and will dash them to pieces like pottery’^[b]—just as I have received authority from my Father.

that one ‘will rule them with an iron scepter and will dash them to pieces like pottery’^[b]

The strong rule with a rod of iron also comes from the Messianic Psalm 2. The image of a broken pottery is equated to rejection of the word of God several times in the Old Testament. Isaiah uses it in Isaiah 30:12-15. Jeremiah shows this act as a symbol of condemnation of this rejection in Jeremiah 19:10-13 where not only the rejection is bad but the people worshipped other gods!

—just as I have received authority from my Father.

So to the overcomers, the coming reign of the Messiah will be shared with true believers under the authority from the Father. See Revelation 1:5, Revelation 3:21, Revelation 20:6, and 1 Corinthians 6:1-3.
