 Affinities that the oldest of these textual traditions share with the Dead Sea Scrolls and Onkelos suggest that the Targum may originate from the same school which finalized the Samaritan Pentateuch itself.Others have placed the origin of the Targum around the beginning of the third century or even later.Extant manuscripts of the Targum are "extremely difficult to use" on account of scribal errors caused by a faulty understanding of Hebrew on the part of the Targum's translators and a faulty understanding of Aramaic on the part of later copyists.
