Since the Hebrew word can mean 'corner' or 'border', the specific place of the attachment of the fringes is unclear. Their exact number is also not specified. Lastly, the passage lacks any instructions on the binding of the fringes, save for the obligation to include "a cord of blue" (Heb. ). The lack of detail on these points suggests that the tying of "tzitzit" was to a great extent Oral Torah until the third to first century BCE with the codifying of the Talmud.
