Greek for ‘four letters’, that is the sacred Hebrew name for God, the consonants YHWH (Exod. 3: 15); but because it was considered too holy to pronounce, Adonai (‘Lord’) was substituted by readers of the text. When the vowels of Adonai were inserted into YHWH the artificial name Jehovah was produced and established for generations by the AV. English translations (except NJB) adopt the convention Lord for the Hebrew Yahweh. (Elohim is rendered ‘God’.) If used, the probable pronunciation of Yahweh was Yehowah.
