My 2016 Easter post contains links leading to biblical and related passages concerning Easter and to correct information on the origin of the word. And this post gives biblical references for the Passion narrative.
And yes, I do know about the "ancient" altar recently discovered in the Church of the Holy Sepulcher (Holy Sepulchre). It's an important discovery, but it is medieval, not ancient, so outside of PaleoJudaica's main range. But if you're interested, follow the link.
UPDATE (18 April): More on the Church of the Holy Sepulcher (Holy Sepulchre) here.
UPDATE (26 April): More on Easter here.
