Type: supporting argument (off-timeline) · Assessment: the historical claim — that reverent non-pronunciation, substituting Adonai ("Lord") and ha-Shem ("the Name") for יהוה in reading, is the older and dominant Jewish practice, from which the Septuagint's Kyrios and every "the LORD" of later Bibles descend — is sound. The normative claim built atop it, that the Name therefore must not be spoken at all, is contested (as is its mirror, that it must be restored — weighed on the companion page).

After the death of the high priest Simeon the Righteous, forty years prior to the destruction of the Temple, the priests ceased to pronounce the Name (Yoma 39b)… From that time the pronunciation of the Name was prohibited. "Whoever pronounces the Name forfeits his portion in the future world" (Sanh. xi. 1). The Septuagint, and after it the New Testament, invariably render [the Name by] κύριος ("the Lord").
— Emil G. Hirsch et al., "Names of God," The Jewish Encyclopedia.1 The interpretation to be weighed: reverent avoidance of the spoken Name is the older and dominant practice — not a late invention or a mere superstition, but the settled usage of Second-Temple and rabbinic Judaism, inherited by the Greek Bible and by Christianity — and (the further, normative step) that this avoidance is warranted rather than an error to be reversed.
The historical half is not a single proponent's thesis but the standing account of the reference literature and of Jewish law itself: the Jewish Encyclopedia and the Catholic Encyclopedia both describe the cessation of pronunciation and the Adonai-substitution as established fact, and the practice is codified in the Mishnah.1 The normative half — that the Name ought not be vocalized — is the living halakhah of rabbinic Judaism (whence the continued use of ha-Shem and Adonai, and the written G-d), and, in a softened form, the long Christian habit of reading and printing "the LORD." It is the rival to be steelmanned against the Sacred-Name and Jehovah's-Witness insistence that the Name must be restored to speech, weighed on the companion page.
1. The Mishnah shows the Name already reserved to one voice, one place, one day. By the time the Mishnah codifies Temple practice, the explicit Name (the Shem ha-Meforash) is spoken only by the high priest, and only in the sanctuary on the Day of Atonement: at his confession over the bull "the priests and the people who were in the courtyard respond after he recites the name of God: Blessed be the name of His glorious kingdom forever and all time" — falling on their faces as they hear it (m. Yoma 3:8; 4:2).2 That the utterance is hedged to this single ritual moment is itself proof that ordinary pronunciation had already stopped.
2. The blasphemy law turns on pronouncing the Name. The Mishnah's court procedure for a blasphemer makes non-pronunciation the very axis of the offense: "One who blasphemes… is not liable unless he utters the name of God and curses it" — so at trial the witnesses testify with a substitute ("Let Yosei smite Yosei"), the court is cleared, and only at the end does the senior witness state "what he heard explicitly" (m. Sanhedrin 7:5). And Abba Shaul lists, among those with no share in the world to come, "one who pronounces the ineffable name of God as it is written, with its letters" (m. Sanhedrin 10:1).3
3. Josephus, writing c. 93, will not commit the Name to his page. Narrating the burning bush, he reports that God "declared to him his holy name, which had never been discovered to men before; concerning which it is not lawful for me to say any more" (Antiquities 2.276) — a Greek-speaking Jew treating the mere writing-out of the Name as forbidden.4
4. The proof-text: Leviticus 24:16, and the double sense of naqab. The rabbinic prohibition was anchored in Leviticus 24:16, "he that blasphemeth the name of the LORD… shall surely be put to death." The load-bearing Hebrew verb is נקב (naqab), whose range runs from "puncture, bore" through "designate, specify" to "curse, blaspheme" — so the verse can be read either as "he who blasphemes the Name" or, as the rabbis took it, "he who pronounces the Name (as it is written)."5 That the "pronounce/name" sense is ancient, not a rabbinic novelty, is shown by the Septuagint, which renders the verb here with ὀνομάζων ("naming"): "he that names the name of the Lord, let him die the death."5
5. The physical evidence at Qumran. The Dead Sea Scrolls already treat the written Name as set apart: copyists write it in archaic paleo-Hebrew letters inside an otherwise square-script text, or replace it with four dots (the tetrapuncta) — devices understood as a warning against pronouncing it. The taboo is thus firmly in place by the 2nd–1st century BC, well before any Christian witness.6 This dovetails with the mechanism already traced on this timeline: it is the vowels of the spoken substitute Adonai that the Masoretes later pointed onto the consonants YHWH, producing the qere perpetuum weighed under "Jehovah" as a hybrid vocalization.
What holds (the historical claim). That reverent non-pronunciation is the older and dominant Jewish practice is as well-attested as anything in the history of the Name: the Mishnah's ritual reservation and blasphemy law, Josephus' refusal, the Qumran scribal devices, the Septuagint's blanket Kyrios, and the Masoretic pointing all converge on it, and they span the 3rd century BC to the early rabbinic period from independent directions. The Christian "the LORD" is the direct heir of this Jewish Adonai-substitution, by way of the Greek Kyrios. On the descriptive question — was avoidance the settled ancient practice? — the answer is unambiguously yes, and this half of the interpretation is sound.
What is genuinely disputed (the normative claim). The step from "this is the older practice" to "this is the warranted practice, the Name ought not be spoken" is a different and contested claim, and the argument should not smuggle the second in on the first's credit. Three honest counterweights: (a) the biblical text itself repeatedly speaks and commands the Name (the burning-bush "this is my name for ever," Exodus 3:15; the theophoric names; "Hallelu-Yah"), and the pre-exilic evidence — the Lachish letters, the theophoric onomastics — shows Israelites using it freely, so the avoidance is a later development, not the original biblical norm (its antiquity is relative to the Second Temple, not to Sinai). (b) The reading of Leviticus 24:16 that grounds the prohibition is the less-natural one: in context the verse concerns the blasphemer who "cursed" (v. 11), so "blaspheme," not bare "pronounce," is the more probable sense — the rabbinic "do not pronounce at all" leans on the verb's possible meaning, not its likeliest one. (c) A practice can be genuinely ancient and dominant and still be a development one is free to weigh rather than simply obey; that it is old does not, by itself, make it obligatory. So the normative claim — on either side — is contested: the avoidance is warranted as reverence, overreaching if pressed as an absolute prohibition; and the mirror-image insistence that the Name must be restored to speech is weighed, and likewise found contested, on the companion page.
Sound — as a historical claim; contested as a norm. Reverent avoidance of the spoken Name, reading Adonai / ha-Shem in its place, is demonstrably the older and dominant practice of Second-Temple and rabbinic Judaism, inherited by the Septuagint's Kyrios and by the Christian "the LORD"; that descriptive thesis rests on converging Mishnaic, Josephan, Qumran, Septuagintal, and Masoretic evidence and is sound. What does not follow automatically is the normative verdict that the Name must therefore never be spoken: that reading leans on the weaker sense of naqab in Leviticus 24:16, runs against the Bible's own free use of the Name, and is a Second-Temple development rather than the original norm — so it is genuinely contested, as is its restorationist mirror. Keep the two claims apart: the history is settled, the obligation is not.
