When the Bible was first written, there were no chapters or verses as today. In fact, many of the early, handwritten manuscripts were written without spaces between the words! Stephen Langton divided the Bible into chapters about A.D. 1228. The Old Testament was divided into verses by R. Nathan in A.D. 1448, and Robert Stephanus divided the New Testament into verses in A.D. 1551. The first complete Bible with chapter and verse divisions was the Geneva Bible of A.D. 1560.
