The division of major sections of the OT (e.g. the Pentateuch) into Books was associated with the amount of material which would fit on to a single scroll. When the Hebrew was translated into Greek, which takes more space than Hebrew, some Books (e.g. Sam.) were divided into two. Conversely single items were collected into Books. Chapter divisions originated in Christian Bibles. Introduced for ease of reference, they followed various systems, e.g. that of the Eusebian canons. That in current use is attributed to Stephen Langton (d. 1228). Verse numbers were first used by Rabbi Nathan in his concordance of the Hebrew Bible in the mid-15th cent. These were used for the OT in the French (1553) and Latin (1555) Bibles printed by Robert Estienne (Stephanus). For the NT he used his own verse numbers in his 1551 edition. These have remained in use ever since. The Geneva Bible (1560) was the first English Bible to have numbered verses throughout.
