In the oldest Hebrew manuscripts (Masoretic), the Old Testament was divided into verses; however, the verses were not numbered. The verses were marked by the soph pasuq, which is a double point ( : ). In the Pentateuch of these ancient Masorectic texts, the number of verses of the parashioth would be written at the end of the parashioth. This notation helped the scribe make an accurate copy, specifically to guard against the addition of verses, and helped the teacher read and remember all the verses of the parashioth.
It is theorized that the history of the Hebrew text goes as follows: 1) scripto continua, 2) the separation of words and the introduction of vowel-letters, and 3) verse division.
