1 Pedro 2

1 Pedro 2:4

Those of the stones that were dragged out of the depths, they placed in the building just as they were: for they were polished and fitted exactly into the other stones, and became so united one with another that the lines of juncture could not be perceived. And in this way the building of the tower looked as if it were made out of one stone. — Shepherd of Hermas, Vision 3
