In reply to your 2/05 post Will the passover still be eaten in the new Jerusalem? (fivedoves.com) in my opinion I don't think the passover will be eaten in New Jerusalem after Jesus' 1,000 year reign on Earth.  According to Rev. 21:1-2, there will be a new heaven and a new earth: for the first heaven are passed away; and there is no more sea at which new Jerusalem comes down from God out of heaven.  Then Rev. 21:4 tells us there shall be no more death for the former things are passed away.

Since there shall be no more death at this time, then the animals used for animal sacrifice for the Passover will no longer be sacrificed and killed.
