"Kyrios" appears over 700 times in the New Testament, and in a few instances some Greek manuscripts also use the term in place of "Theos". The consistency in rendering "YHWH" as "Κύριος" in all New Testament references would be difficult to explain if there were not already either an established tradition to read "Κύριος" where "YHWH" appears in a Greek manuscript, or an established body of texts with "Κύριος" already in the Greek. "Κύριος" is not an exact synonym of the Hebrew Tetragrammaton.
