  • Tiberian: tāw[1]

Forms

תָּו (tāw) noun, masculine[1][2] With suffix תָּוִי “my mark” (Job 31:35); with the article הַתָּו (Ezekiel 9:6).[3][2]

Etymology

It is an old Semitic noun for a mark: Huehnergard reconstructs it for Central Semitic as *taww- (“mark, sign”), the source, through Phoenician, of the name of the last letter of the alphabet.[4] HALOT explains that the last letter of the Old Canaanite alphabet had the shape of a cross, a simple mark used by herdsmen, and compares Arabic تَوّ (taww, “single, separate item”).[3] Gesenius–Buhl and Klein compare instead تِوَاء (tiwāʾ, “brand”), the mark burned on livestock.[5][6] The verb תָּוָה (tāwâ, “to make a mark”) is a denominative from the noun.[7][2]

Earliest recorded meaning

It occurs three times.[1] In Ezekiel's vision a man clothed in linen is told wəhiṯwîṯā tāw ʿal-miṣḥôṯ hāʾănāšîm, “and put a mark on the foreheads of the men” who groan over the city's abominations, and those who have the mark are spared (Ezekiel 9:4, 9:6).[1][3] HALOT takes it as a sign of protection given to those who professed their faith in the LORD.[3] In Job 31:35 Job ends his defence with hen-tāwî, “here is my mark”, his signature on the case.[1][3][2]

Semantic evolution

HALOT, after Keel, describes the mark as a sign of ownership or belonging, used in cult and in daily life.[3] For Job 31:35 Fohrer compared the nail impressions that signed Babylonian clay tablets, and Koehler thought of a house mark;[1] Driver's conjecture of a noun for “desire”, which would fit the Vulgate's desiderium meum, is rejected by HALOT.[3] The Septuagint renders the mark of Ezekiel 9:4 by Ancient Greek σημεῖον (sēmeîon).[1] The Damascus Document quotes Ezekiel's mark, and the Dead Sea Scrolls have the word in a few fragments.[3][8] In Rabbinic Hebrew tāw is both a mark and the name of the last letter, so called after its old shape.[9][3] Today Modern Hebrew תו (tav) is also a musical note.[6][10]
