It is commonly asserted that the Jews do not speak the name of God (Tetragramaton) in reverence to the Name. It is even treated as taboo to speak or pronounce, or utter the name.
Yet, in the Bible reverential people are shown as using the name, attesting to the name, swearing by the name, "as YHWH lives..." praising the name, exalting the name, proclaiming the name...
Does someone in Rabbinic tradition prohibit speaking and pronouncing the name of God (the Tetragramaton). If so, where? When was it first prohibitted? Where is the prohibition found, or where was it first documented? What does it say. What are the subsequent rabbinic addresses regarding this. What were the surrounding circumstances to the prohibition? How far back can it be traced historically with evidence?

All of the quotes I have seen only reinforce God's command to not take His name in vain. They only warn against speaking it falsely, needlessly, disrespectfully or incorrectly.
They never prohibit speaking God's name in ways that God proscribes--swearing by His name, praising His name, proclaiming His name...
This is precisely what I would expect from Jewish sages, men of wisdom and integrity, who would never contradict God's word.
