Jez

Diminutive of JEREMY.

JEREMY   male   English, Biblical
Medieval English form of JEREMIAH, and the form used in some English versions of the New Testament.
JEREMIAH   male   English, Biblical
From the Hebrew name יִרְמְיָהוּ (Yirmiyahu) which meant "YAHWEH has uplifted". This is the name of one of the major prophets of the Old Testament, the author of the Book of Jeremiah and the Book of Lamentations (supposedly). He lived to see the Babylonian destruction of Jerusalem in the 6th century BC.

In England, though the vernacular form Jeremy had been occasionally used since the 13th century, the form Jeremiah was not common until after the Protestant Reformation.
YAHWEH   male   Theology
A name of the Hebrew God, represented in Hebrew by the tetragrammaton ("four letters") יהוה (Yod Heh Vav Heh), which was transliterated into Roman script as Y H W H. Because it was considered blasphemous to utter the name of God, it was only written and never spoken, which resulted in the original pronunciation becoming lost. The name may have originally been derived from the old Semitic root הוה (hawah) meaning "to be" or "to become".
