[Hope]

There is no reason for the New Testament authors not to mention it, even if it is a sacred name. The reason it is not mentioned is because in the New Testament Jesus replaces Yahweh. That's the New Testament revelation, or the updated biblical version, namely, that Jesus is God (Yahweh)!

You reject Yahweh and Allah.

But you promote a man who ate, burp, sneezed and defecated
