Teth

TETH tāth (ט, [Teth]). The ninth letter of the Heb. alphabet. It appears in the KJV at the head of the ninth section of Psalm 119, in which section each verse in the Heb. begins with this letter.

International Standard Bible Encyclopedia (1915)

The 9th letter of the Hebrew alphabet; transliterated in this Encyclopedia as "T" (a more intense "t"). It came also to be used for the number 9; and with waw ("w") for 15, with zayin ("z") for 16 (i.e. 9 plus 6 and 9 plus 7) to avoid forming regular series with the abbreviation for Yahweh. For name, etc., see Alphabet.
