"It thus becomes possible to determine with a fair degree of certainty the historical pronunciation of the Tetragrammaton, the results agreeing with the statement of Ex. iii. 14, in which Yhwh terms Himself "I will be", a phrase which is immediately preceded by the fuller term "I will be that I will be", or, as in the English versions, "I am" and "I am that I am". The name is accordingly derived from the root (= ), and is regarded as an imperfect. This passage is decisive for the pronunciation "Yahweh"; for the etymology was undoubtedly based on the known word. The oldest exegetes, such as Onḳelos, and the Targumim of Jerusalem and pseudo-Jonathan regard "Ehyeh" and "Ehyeh asher Ehyeh" as the name of the Divinity, and accept the etymology of "hayah" = "to be" (comp. Samuel b. Meïr, commentary on Ex. iii. 14)."
