The God referenced in the bible does, in fact, have a name.

The Tetragrammaton is the usual reference to the Hebrew name for God, which is spelled (in the Hebrew alphabet): (yodh) (heh) (vav) (heh) or (reading right to left = YHVH, or with the Biblical Hebrew pronunciation, YHWH). It is the distinctive personal name of the God of Israel.

In Judaism, the Tetragrammaton is the ineffable Name of God, and is therefore not to be spoken, except by the High Priest within the Holy of Holies in the Tabernacle and Temple in Jerusalem on Yom Kippur. In the reading aloud of the scripture or in prayer, it is replaced with Adonai ("My Lords", commonly rendered as "The LORD" in most modern English translations) or occasionally replaced with "Elohim" (GOD).

Various English spellings of the Tetragrammaton include Iehouah [AD 1530], Iehovah [1611], and Jehovah [1769]. Yahweh, Yehovah, and Y'hovah are also used.

The following works, either always or sometimes, transcribe the Tetragrammaton as Jehovah:
